  • New:
  • :matches-path(...):
  • New cosmetic procedural operator, :matches-path(...). See "Add $path modifier of Adguard or any equivalents of this".
  • Node.js:
  • A new Node.js package will now published with every release. The package allows to import and use uBO's static and dynamic filtering engines into Node.js. This is currently minimal and a first iteration, and issues regarding the Node.js package are accepted in order to improve usability of uBO's filtering engines in a Node.js package. The ability to run code from a Node.js package also opens the door to have test coverage in uBO.
  • For now the package can be downloaded and unzipped locally. Once installed, you can execute node test in the root of the package to verify that the static network filtering engine works properly. For usage, refer to the test.js, or ublock.js used in Cliqz's benchmark.
  • Since I have little experience with dealing with Node.js environment/packages, thanks to @mjethani for assistance.

  • Closed as fixed:
  • Core:
  • '$popup' not working
  • Service worker "tabless" requests with correct context are still modified when page is whitelisted
  • Back/Forward navigation does not work between Ublock Origin option pages
  • csp_report filter created via logger is marked as invalid
  • Extreme popup blocking - uBo dashboard is blocked when popups are
  • ipv6 fe80::1%lo0 localhost from hosts file is marked as error line
  • Whitespaces are now stripped from blocking-rule URLs, causing rules targeting whitespaces to fail and/or block extremely broadly
  • uBO's dashboard does not refresh custom filters in real-time
  • Element picker/zapper don't work if cosmetic filtering is disabled
  • Logger always highlights first match
  • Static filtering: Cannot prevent my filter from strict-blocking

New in uBlock Origin 1.36.0 (Jun 22, 2021)

  • Closed as fixed:
  • Chromium:
  • uBlock does not load adminSettings at first run
  • Firefox:
  • Bizarre perf drain when ajaxing in 90,000 DOM nodes in a react component
  • Core:

  • Stop autoplay for unset media source with no-large-media-elements
  • Use CDN URLs as fall back URLs

New in uBlock Origin 1.35.0 (Apr 22, 2021)

  • New:
  • New filtering ability to remove specific response headers from document resources. Example:
  • example.com##^responseheader(refresh)
  • Only the following response headers are allowed to be removed, anything else will cause the filter to be invalid and discarded:
  • location
  • refresh
  • report-to
  • set-cookie
  • Chromium-based browsers:
  • Google's FLoC is defused by default. Websites will be able to use the FLoC API (only if already present), but will be unable to get a result from it -- uBO causes the API to always fail as if there was no FLoC data available.
  • If your Chromium-based browser supports the FLoC API, this is the result you should get with uBO when testing with EFF's "Am I FLoCed?" (assuming you did not disable uBO's "uBlock filters -- Privacy" list).
  • Additionally, uBO causes all websites to opt-out of being part of FLoC calculation by injecting the appropriate response header.
  • You can opt-in to FLoC by creating the appropriate exception filter, see commit message for details.
  • Closed as fixed:
  • Block FLoC checks in Chrome/uBO
  • json-prune doesn't remove all properties by full wildcard

  • Whitelisting a site on Chromium Edge still blocks resources fetched by service worker

New in uBlock Origin 1.33.0 (Feb 3, 2021)

  • Support for match-case filter option, but only for regex-based static network filters.
  • Ability to auto-complete (Ctrl-Spacebar) hostname values for origin-related options in static filter editor according to currently opened tabs.
  • Changes:
  • Dynamic filtering:
  • Noop-ing a blocked 3rd-party cell will cause uBO to immediately attempt to reload blocked stylesheets, if any. This will also occurs when the noop-ing is done through the "relax blocking mode" shortcut, in which case uBO will no longer force a reload the whole page. You can restore the previous behavior by modifying the advanced setting blockingProfiles.
  • Closed as fixed:
  • Core:
  • GitHub dark mode makes whole page invisible when element picker is active
  • :watch-attr() stopped working (regression in 1.30.0)
  • uBO should ignore redirect= directives with unrecognized redirect token
  • Can't load the images

  • For existing installations, both removed malware lists will be moved to the Custom section if you still have them enabled. It is recommended you remove these lists from your Custom lists -- only you can do this, uBO does not remove lists which are currently enabled.

  • Remove Malware domains
  • Remove Malware Domain List

New in uBlock Origin 1.28.0 (Jul 10, 2020)

  • ##script:inject(...), which has been deprecated in favor of ##+js(...) for more than two years, is no longer supported.
  • It's no longer possible to point-and-click to create allow (green) rules from within the popup panel by default.

You can get back temporarily the ability to create allow rules from within the popup panel by tapping twice the Ctrl key.
  • Improved syntax highlighting of static filters in "My filters" and asset viewer. Additionally, in "My filters":
  • Ability to toggle commenting out of filter(s) by pressing the Tab key
  • Auto-completion using Ctrl-Space, this works for:

New in uBlock Origin 1.26.2 (Apr 21, 2020)

  • The sole purpose of this release is to ensure an up to date version of EasyList is shipped as part of the package.
  • An obsolete version of EasyList was shipped with uBO 1.26.0 and this was causing Google fonts to be unduly blocked everywhere after installing uBO for the first time.
  • Though forcing an update of filter lists would solve the issue, Google fonts should not be blocked out of the box without having to force an update of filter lists.

New in uBlock Origin 1.26.0 (Apr 7, 2020)

  • Closed as fixed:
  • Remove Adblock Warning Removal
  • Add a way to blanket-except blocked cname-based requests

  • Fix token array being too small for very long URL

New in uBlock Origin 1.22.5 RC 0 (Oct 1, 2019)

  • NEW:
  • Static filter option elemhide as per ABP semantic
  • The elemhide option is now fully supported, rather than being an alias of generichide. The elemhide option will be internally converted into two filters, generichide and specifichide. There have been cases raised by filter list maintainers where specifichide would be useful. Additionally, the filter options elemhide, generichide and specifichide can be aliased with ehide, ghide and shide respectively. (generichide appears over 1,300 times just in "uBlock filters".)
  • CLOSED AS FIXED:
  • Prevent uBO from being reloaded mid-session:
  • A new advanced setting -- extensionUpdateForceReload -- can be used to override this new behavior.
  • Comply with new security requirements for Chrome:
  • The changes benefit all platforms.
  • Add advanced setting to control logger popup type
  • Ignoring ping filters

New in uBlock Origin 1.22.4 (Sep 27, 2019)

  • This is an emergency fix.
  • The issue was fixed in dev build days ago, and it was originally deemed to not be a serious regression.
  • However as reported by a user on Reddit, the issue was affecting more than just the logging of cosmetic filters, it was completely breaking cosmetic filtering when the two following conditions were met:
  • uBO's own logger was opened; AND
  • Procedural cosmetic filters were injected on the page.

New in uBlock Origin 1.22.2 (Sep 9, 2019)

  • Emergency fix in ac7825c: redirection rules could be ignored under some circumstances. Regression from 3e5c9e0.

New in uBlock Origin 1.22.0 (Sep 2, 2019)

  • New:
  • Toolbar icon badge color:
  • The toolbar icon badge color will now reflect the current blocking mode. This should help with usage of the "Relax blocking mode" shortcut. The way uBO relaxes the current blocking mode is configurable through the advanced setting blockingProfiles.
  • Static network filter options:
  • redirect-rule=:
  • This new option allows to create a pure redirect directive, without a corresponding block filter as would be the case with the redirect= option. For example, consider the following filter:
  • ||example.com/ads.js$script,redirect=noop.js
  • The above filter will result in a block filter ||example.com/ads.js$script and a matching redirect directive. Now consider this following filter:
  • ||example.com/ads.js$script,redirect-rule=noop.js
  • The above filter will not cause a block filter to be created, only a redirect directive will be created. Standalone redirect directives are useful when the blocking of a resource is optional but we still want the resource to be redirected should it ever be blocked by whatever mean -- whether through a separate block filter, a dynamic filtering rule, etc.
  • empty and mp4:
  • Support for AdGuard's empty and mp4 filter option has been added.
  • !#if false ... !#endif:
  • Support for the directive !#if false to easily disable a block of filters, which is more convenient than having to delete them all or prefix them all with !.
  • Scriptlet injection:
  • Ability to wholly disable scriptlet injection for a given site using broad scriptlet injection exception:
  • example.com#@#+js()
  • It is also possible to disable scriptlet injection everywhere with a generic exception:
  • #@#+js()
  • This is useful when creating specific exception filters is inconvenient.
  • Closed as fixed:
  • Support AdGuard's empty & mp4 static filter options
  • Add ability to bypass browser cache when fetching a resource
  • Extension icon doesn't revert back when the domain is removed from Whitelist tab
  • Dead code in assets.js
  • Popup panel closing when forcing a reload
  • uBlock does not appear to honor overriding default assets.json via Chrome policy
  • uBo logger show not used :style(...) filters

New in uBlock Origin 1.17.0 (Sep 26, 2018)

  • New:
  • Per-site JavaScript master switch:
  • A new per-site switch has been added to the popup panel, which acts as a master switch for JavaScript for the current site.
  • This master switch has precedence over dynamic filtering rules and static filters related to script resources.
  • Furthermore, when JavaScript is disabled through this master switch, noscript tags will be honoured on a page (as opposed to when just using filters/rules to block script resources).
  • As with some other per-site switches, the default state of per-site JavaScript master switch can be set in the Settings pane, thus allowing to disable JavaScript everywhere by default, and enable on a per-site basis.
  • JavaScript master switch rules appear as no-scripting: [hostname] true entries in the My rules pane.
  • Temporarily toggle per-site switches:
  • From now on, changes to the state of per-site switches will be deemed temporary if and only if the overview panel is visible, regardless of whether "advanced user" mode is enabled.
  • When the overview panel is not visible, toggling a per-site switch will cause the change to be permanent (i.e. same behavior as before).
  • However, when the overview panel is visible, toggling a per-site switch will cause the change to be temporary. In such case, there will be an eraser and a padlock icon in the overview pane, which can be used to revert or persist the current state of all the per-site switches.
  • Cache storage compression:
  • A new advanced setting: cacheStorageCompression, default to true. When true, uBO will lz4-compress data before storing it in its cache storage in supported platforms. Currently, the only supported platform is Firefox/Firefox for Android.
  • The cache storage is used for storing downloaded filter lists, compiled filter lists, selfies. See https://github.com/uBlockOrigin/uBlock-issues/issues/141 for related discussion.

New in uBlock Origin 1.16.20 (Aug 27, 2018)

  • Decided to create an emergency fix for a bug which was spotted for uMatrix but which also affects uBO: "My rules tab hangs with cloud storage support"
  • If using cloud storage, there is a small probability uBO could be stuck in an infinite loop when reading back the data from the cloud storage.
  • If the bug is triggered, uBO could be stuck in an infinite loop in its main process, thus preventing it from doing its job.
  • This is not a regression, but rather a bug that has been hiding in there since quite a long time.

New in uBlock Origin 1.16.16 (Aug 13, 2018)

  • The release version of uBO on AMO is not allowed to update its resources.txt asset. This means the version shipped with the extension must be used. However, uBO compile and cache the data in resources.txt, and unless the cache is invalidated, uBO will keep using a potentially out of date version of resources.txt. This has been fixed by unconditionally invalidating the cache when a new version of uBO is detected.

Set to true to bring back scriptlet injection through stream filtering as was the default before 1.15.10. A fix has also been added to resolve https://github.com/uBlockOrigin/uAssets/issues/1492, which was the main reason to disable stream filtering-based scriptlets injection in 1.15.10.
  • Integration of CodeMirror in uBO's dashboard. Please do not open feature requests related to this.

  • New HTML filtering Ability to remove DOM elements from a source document before it is parsed by the browser. The platform must support an extension API to modify the response body on the fly. Currently only Firefox 57+ allows this. The filter syntax is similar to cosmetic filtering, except that the character ^ is used before a valid selector to denote that the filter is to be applied to the source data. Contrary to cosmetic filtering, with HTML filtering the elements matching a selector are removed from the source.
  • SUB-FILTER LISTS:
  • Ability for filter list maintainers to force uBO to load extra filter lists from within a filter list, using an !#include directive. Example: !#include adblock_ublock.txt When uBO encounters the above directive inside a filter list, it tells uBO to load the extra filter list and append it to the current one. The main purpose of such directive is to allow filter list maintainers to be able to make use of uBO's extended filter syntax, without forfeiting the ABP-compatibility of their main filter list: ABP will ignore such directive since it will be seen as a mere comment. All the details of the new directives syntax is being fleshed out at https://github.com/AdguardTeam/AdguardBrowserExtension/issues/917. At this point only !#include is implemented by uBO, because it solves immediately a current issue by simplifying the work of filter list maintainers who want to make use of uBO's extended filter syntax. Important: uBO forbids sublists which are outside the directory of the main list. Typically, filter list maintainers will just use a single file name, as seen in the example above, in which case same-origin and same directory is implicit. Changes Logger The logger can now be opened in a sidebar on Firefox. Just open the side bar and "uBlock₀ -- Logger" will be available as a choice.
  • Enhancements:
  • A new entry in the tab selector: "Current tab": This will cause the logger to automatically filter out rows which do not belong to the currently active tab.
  • The rows related to behind-the-scene scope are now always shown.
  • If you close a tab while "Current tab" is selected, the resulting void rows will be automatically deleted.
  • You can expand/collapse a single row by clicking on the time stamp cell.

New in uBlock Origin 1.14.19b8 Beta (Nov 20, 2017)

  • CHANGES:
  • The filter list "AAK-Cont Filters For uBlock Origin" has been removed from stock filter lists, it is no longer maintained. See #3241. Note that uBO is equipped to deal with anti-blockers, it's just a matter of users reporting instances to volunteer maintainers. Everybody is welcomed to assist in finding solutions to reported filter issues.
  • The DOM inspector has been improved a bit to make it more usable (see #407). Some refactoring was necessary to move forward this part, and as a result the DOM inspector is currently not available on legacy Firefox. This will be addressed only as time allow. Note that I still consider the DOM inspector to be work in progress.

New in uBlock Origin 1.14.11b1 Beta (Sep 17, 2017)

  • CHANGES IN SELECTION OF STOCK FILTER LISTS:
  • Added:
  • "Adguard Generic Filters". Thanks to Adguard's @ameshkov for going out of his way to make the list specifically for uBO. Both Adguard and uBO share some extended filter syntax, and as such uBO users do benefit from Adguard's filter lists.
  • "Adguard Annoyances" (in "Annoyances" section)
  • "Fanboy's Cookiemonster" (in "Annoyances" section)
  • Removed:
  • "EasyList without element hiding rules" (not very useful)
  • "Reek's AAK" (no longer maintained)
  • "uBlock Protector List" (it required Chrom[ium|e], uBO must be browser vendor agnostic)
  • "EU: Prebake" (no longer maintained)
  • For whoever has one of the removed list selected, it will be moved to the "Custom" section (i.e. converted into an imported filter list).

New in uBlock Origin 1.14.11b0 Beta (Sep 14, 2017)

New in uBlock Origin 1.14.10 (Sep 13, 2017)

  • Firefox 52-56 (webext):
  • Code review-related fix: a test was introduced in #2950, which purpose was meant to punycode only if required for Firefox 52-56. Turns out the regex used in the test was flawed and this caused the punycoding code path to be always taken, meaning a pointless added overhead in network request handlers for when no punycoding is needed. Fixed with 04a41d8.

New in uBlock Origin 1.14.0 (Sep 1, 2017)

  • CLOSED AS FIXED:
  • Firefox:

  • Core:
  • Fixed bad test (regression from fdcc951).
  • Generate better regex for hostname-anchored generic filters (there are ~4,500 such filters with default filter lists).
  • Update 1: Apparently there are more issues for people using the 32-bit version of Firefox. See https://bugzilla.mozilla.org/show_bug.cgi?id=1371255#c21. Please report such issues to Firefox devs, there is nothing I can do. I can only recommend to people with Firefox 32-bit to stay on 1.13.8, or optionally install uBlock.firefox.xpi (legacy version) from Releases section.
  • Update 2: Also, there appears to be a limit to how much data can be stored in indexedDB, so if you have many more extra filter lists, not all of them will be able to load, and this can also break the future updating of whichever filter lists could load. In short, total mess. Just as I feared, there are issues with indexedDB.

New in uBlock Origin 1.13.9b0 Beta (Jul 21, 2017)

  • Firefox WebExtensions:
  • The webext (-hybrid) version of uBO has been released to the dev channel on AMO.
  • The first time it executes, there might be a noticeable delay: this is caused by the fact that uBO will import all the data from legacy storage, into webext storage. This is done only the first time the webext (-hybrid) version is executed, after this the import step will be skipped. If you subsequently remove uBO, this will cause the webext storage to be removed by Firefox, and upon re-installing the webext version, the import code will again kick in.
  • Note that uBO/webext will still be labelled as "Legacy" in about:addons, because uBO/webext is really a webext-hybrid extension. Once the legacy storage has been imported by the thin legacy wrapper, uBO will fully function as a pure webext extension despite the "Legacy" label.
  • The legacy storage is left untouched by uBO/webext, so you can always go back to uBO/legacy (stable release) if you do not want to use the webext version in the short term.

New in uBlock Origin 1.13.8 (Jul 18, 2017)

  • Stock filter lists:
  • I added code to enable me to remove stock filter lists in a seamless way for users. There are a couple of stock filter lists I wish to remove (because no longer maintained), but I refrain from doing so because it would be rude to remove a stock filter list which might be enabled for some users out there. The added code will convert removed stock filter lists which are enabled into imported filter lists, so that no change occurs in the resulting filterset from a user's point of view.
  • Firefox WebExtensions:
  • I received an email from Firefox informing me that on September 1st, 2017, all the extensions having "featured" status which are not converted to webext on AMO will lose their "featured" status. At this point, I am considering pushing the webext-hybrid version of uBO into uBO's dev channel on AMO. I don't think the webext-hybrid qualifies as a webext, but is a necessary step to migrate user data seamlessly.

New in uBlock Origin 1.13.2 (Jun 22, 2017)

  • Closed as fixed:
  • Chromium-based browsers
  • Inconvenient default hotkey mapping activation
  • Reportedly, the default keyboard shortcut I picked do not work for all locales. Consequently I removed default shortcuts and users will have to pick whatever work for them.
  • Important: For those already affected by the issue, the suggested shortcuts were already added and won't be removed with this update. You will have to remove or re-assign yourself by clicking "Keyboard shortcuts" link in the page chrome://extensions -- the link is at the bottom of the page.
  • Google Chrome, with uBO installed from Chrome store:
  • The extension is disabled in chrome
  • More specifically, this is due to a Chromium bug, see #2720 (comment).
  • Chromium bug: https://bugs.chromium.org/p/chromium/issues/detail?id=720597.
  • As reported by users, if you click Repair, you will lose all your settings in uBO, see #2720 (comment).
  • Consequently, force an update of the extension, do not click "Repair" -- my understanding so far is that forcing an update will not cause all your uBO settings to be lost.
  • 1.13.0 had been released to only 20% of all Chrome store users.
  • In the unfortunate event all your uBO settings were lost, you will have to restore them. If you do not have a backup of your settings, you may give this a try.

New in uBlock Origin 1.13.0 (Jun 20, 2017)

  • NEW:
  • New static network filter option: csp=:
  • This new filter option allows to inject any Content Security Policy header in pages matching the filter. See #1930 (comment) for discussion about the rationale behind this new filter option.
  • Some existing filters may be converted internally to csp=-based filters by uBO. For example, a filter such as |blob:$script,[...] will be converted to *$csp=script-src 'self' * data: 'unsafe-inline' 'unsafe-eval',[...], in order to enforce the blocking of blob:-based URIs for scripts, something otherwise not possible through the chrome.webRequest API.
  • Element zapper:
  • Ability to zap DOM elements on the current page.
  • The purpose is to quickly deal with the removal of nuisance elements on a page without having to create one or more filters: see documentation.
  • Support for keyboard shortcuts:
  • Enter element zapper mode: default to Alt-Z.
  • Enter element picker mode: default to Alt-X.
  • Open logger: default to Alt-L
  • For Chromium or WebExtension-compatible browsers:
  • You can re-configure the shortcuts through the browser API. For Chromium-based browsers, go to chrome://extensions, scroll down then click on "Keyboard shortcuts". I suppose this depends of the browser, you will have to investigate.
  • For Firefox (non-webext version):
  • You can re-configure the default shortcuts for the above commands by opening about:config and filtering with extensions.ublock0. The default shortcuts are built-in, if you want to re-defined or un-set them, you will have to create the entries:
  • extensions.ublock0.shortcuts.launch-element-zapper
  • extensions.ublock0.shortcuts.launch-element-picker
  • extensions.ublock0.shortcuts.launch-logger
  • To disable a built-in shortcut, set the value to -.
  • To reset to a default shortcut, reset the corresponding entry in about:config.
  • These about:config shortcut values are read only at launch time, so you will have to restart uBO for the changes to take effect.
  • CHANGES:
  • Some refactoring work of static filtering engine:
  • to be more modular and hence make it easier to extent filter syntax
  • to lessen overhead overall
  • to address #2598, #2630
  • to extend filter syntax to support csp= filter option.
  • This is an important refactoring. At first my intention was to add support for csp= filter syntax, but this required some refactoring, and while at it I decided to address a lot of other details regarding static filtering engine which I meant to address since a while, hence the extent of the changes to the code.
  • As a result, I have observed that baseline memory footprint of uBO itself is 5-6 MB less with 1.13.0 compared to 1.12.4 on both Chromium and Firefox (Linux 64-bit, default uBO settings).
  • Improved compatibility with Adguard's filter lists:
  • See #2624. I do plan to add Adguard's English filter lists to uBO's stock filter lists for the next stable release.
  • Given that both Adguard and uBO support advanced filter syntax not supported by ABP (which advanced syntax benefit end users and make a filter list maintainer's life easier), and given that EasyList maintainers are limiting themselves to support no more than what ABP can support, enabling Adguard's filter lists as default list in their respective locale is something I am considering.
  • CLOSED AS FIXED:
  • Firefox Nightly:
  • uBO toolbar menu is too wide again
  • Menu has too much space on the top and bottom
  • Core:
  • ||*tube.com^ for youtube.com is not working
  • [Performance] tokenize URLs to numeric values instead of substring values
  • Support Adguard's [-ext-has="..."] syntax => convert to uBO's :if(...)
  • ABP Subscription Links Not Understood
  • uBlock Origin for Google Chrome and apiBreaker
  • [Performance] Mind the potential negative consequences of String.slice()
  • Dynamic filtering allow-all still blocks ads, log shows images allowed workers blocked
  • Cannot set exemptions to strict blocks

New in uBlock Origin 1.12.2 (Apr 25, 2017)

  • No code change, just a re-package with more recent filter lists to ensure uBlock Origin works out of the box with EasyPrivacy without breaking Facebook upload feature: a filter in EasyPrivacy was causing a false positive.

New in uBlock Origin 1.12.1 (Apr 18, 2017)

  • No code change, just a re-package with more recent filter lists to ensure uBlock Origin works out of the box with EasyPrivacy without breaking Facebook upload feature: a filter in EasyPrivacy was causing a false positive.
  • For existing installations, just force an update of EasyPrivacy.
  • Did not look into the details, but at first glance it seems the false positive appeared as a result of Facebook changing its code. It's unlikely sites such as Facebook (who would rather not encourage the use of blockers) would test their pages when using a blocker in order to ensure their site still works fine with a blocker.
  • A whole lot of users have no clue that most blockers work based on filter lists which can cause false positives. The Facebook issue would have happened with any blocker making use of EasyPrivacy.
  • False positives must be reported to filter list maintainers (not here), and often just forcing an update of filter lists may resolve an issue (because maybe somebody else reported the issue and it was fixed by maintainers).

New in uBlock Origin 1.12.0 (Apr 10, 2017)

  • New static network filter option: badfilter. Using this option will prevent another filter to be loaded in memory. See uBlockOrigin/uAssets#192 for rationale for having such a filter option.
  • Chromium/Firefox WebExtension:
  • Ability to support more request types from webRequest API: csp-report, font, media, websocket, and actually whatever is part of webRequest.ResourceType. This means uBO will be able to natively filter websocket connection attempts starting with Chromium 58.
  • Firefox:
  • The webext version for Firefox has been converted into a hybrid version, to allow seamless migration of uBO's settings/data from a legacy extension to webext extension. Update: due to auto-update snafu, the webext version of uBO has been given a different id than the official one, this will guarantee that auto-update won't cause issue (you will have to update manually if using the webext version).
  • Important: If you install the webext version of uBO (you need the most recent build of Nightly), this is what will happen:
  • When you launch uBO/webext for the first time, it will read all your settings/data from the old storage and migrate them to the new webext storage. This happens only if uBO/webext can find a file named ublock0.sqlite. This will happens only once, the first time you install uBO/webext. Depending of how much data there is to migrate, this may cause your browser to work hard during that first launch and delay readiness.
  • Once the data from the uBO/legacy has been migrated to uBO/webext, each version of uBO will only see its own data, meaning no change in settings in one version will be seen by the other version. If you remove uBO/webext, this also removes the storage associated to it, meaning re-installing uBO/webext following removal will cause the storage migration code to kick in again.
  • Closed as fixed:
  • Chromium:
  • Use the strictest setting for preventing the leakage of private IP addresses through WebRTC. It turns out the use of the strictest setting has (currently) the unforeseen virtuous side-effect of preventing WebRTC-delivered ads on some sites. See uBlockOrigin/uAssets#333 (comment).

  • Chromium:
  • Fix https://bugs.chromium.org/p/project-zero/issues/detail?id=1225&desc=6#c10. No security issue in the case of uBO, but a web page could theoretically mess up with the functioning of uBO's content script (which main purpose is cosmetic filtering).

New in uBlock Origin 1.11.0 (Feb 6, 2017)

  • THE USER INTERFACE OF THE "3RD-PARTY FILTERS" HAS BEEN REVISITED:
  • To render better in devices with smaller screen.
  • Clicking "Update now" is no longer a blocking operation.
  • The home icon is a link to the support site for a given filter list.
  • The clock icon replaces the "purge cache" label: Click to mark a filter list as out-of-date.
  • The custom filter lists input field has been repurposed to import external filter lists, as opposed to declare external filter lists as was the case before: An imported filter list will have an X icon aside its name, to be used to remove the custom filter list.
  • You can now hide unused filter lists by clicking the global filter count at the top.
  • NEW PROCEDURAL COSMETIC FILTER OPERATORS:
  • :has-text(argument): to filter elements according to whether they have a specific text string found in them. Use /.../ to match a literal regular expression instead of plain text.
  • :if()/:if-not(argument): use to implement recursion, argument is itself a valid procedural cosmetic filter, but can also be a plain CSS selector.
  • FIREFOX:
  • Chained unwanted popups not properly filtered
  • CORE:
  • Please enable RU Adlist filter for ex-USSR/CIS locales
  • Assets management refactored
  • Logger timestamps are incorrect when system time zone is not on hour boundary
  • Not blocked websockets (worker)
  • Want to create a regex to whitelist all google but no luck
  • Duplicate filter lists
  • Ads are not blocked on bing.com web searches (issue filed for Edge, but also present on other platforms, those not supporting user styles or shadow DOM):
  • The fix needs to be tested/confirmed for the Edge version.
  • For Chromium-based browsers, use of shadow DOM has been removed in an attempt to simplify/unify generic implementation of the concept of user styles. (can be brought back if feedback shows it's needed).
  • Most reliable and low overhead cosmetic filtering is on modern Firefox (38+), all other platforms (Chromium, Edge, legacy Firefox, Safari) not providing proper "user styles" API rely on same generic implementation.

  • CHANGES:
  • Procedural cosmetic filters can now be chained and recursive (something which was planned).
  • New procedural cosmetic filter operators:
  • :has-text(argument): to filter elements according to whether they have a specific text found in them. Use /.../ to match a regular expression instead of plain text.
  • :if()/:if-not(argument): use to implement recursion, argument is itself a valid procedural cosmetic filter.
  • Any of the operator which accept a string value can also accept of literal regular expression value.
  • The :xpath() operator can now accept a plain CSS selector as prefix (i.e. example.com##.item:xpath(...)), just like all other operators. The XPath evaluation will use whatever element matches the CSS selector as the context node for the XPath.
  • The cost of parsing procedural cosmetic filters has been moved from content script-time to filter list compile-time, i.e. done only once when a filter list is updated.
  • The element picker supports all procedural cosmetic filters, i.e. it will also provide visual feedback as you enter manually such filters in the input field. Invalid filters, procedural or not, will be labelled with a bright red E.
  • Efficient procedural cosmetic filters (or any cosmetic filters really) are the ones which result in the smallest set of nodes to visit. The element picker input field will display the number of elements matching the current filter. The element picker will only consider the entered text up to the first line break, while leaving the rest as is. You can use this feature to break up your filter to find out the size of the resultset of the first part(s) of your filter: the smallest resultset the most efficient is your cosmetic filter.

  • :matches-css now accept no more than one single style property. If more than one style property must be matched on the same node, you will need to chain them (i.e. div##matches-css(...):matches-css(...) -- ability to chain is coming for next release). Since there is only one style property, do not use trailing ;.
  • :matches-css-before() and :matches-css-after() are now also available to specifically match style property for the pseudo elements :before and :after on a node.
  • Support the use of regexes for property matching: if the first and last character of the value to match is /, the value will be deemed to be a literal regular expression which must be matched.

New in uBlock Origin 1.10.0 (Dec 6, 2016)

  • DYNAMIC FILTERING PANE:
  • The dynamic filtering pane in the popup panel is now available in read-only mode to users who did not enable "I am an advanced user" in Settings.
  • The rationale for this change is explained in issue 2010. It still is collapsed by default, but can be brought up by clicking the "requests blocked" or "domains connected" fields in the main area.
  • TEMPLATE-BASED SCRIPTLETS:
  • In order to promote the reuse of injectable scriplets across different sites, it is now possible for a scriptlet to accept arguments. The arguments are comma-separated and appear after the token, for example (a real case): golem.de##script:inject(abort-on-property-write.js, _sp_)
  • In the example above, the scriplet abort-on-property-write.js contains a placeholder for one argument, which placeholder will be replaced with the argument _sp_. Placeholders for scriplets which accept arguments will always be for string values (reminder that injectable scriplets are part of the project, never from an external party).
  • ADVANCED SETTINGS:
  • A new "Advanced settings" pane, available only to advanced users. It contains settings which are experimental, or which are of interest to advanced users who want more control over how uBO behaves internally. I do not want to bloat the Settings pane in the dashboard with settings which are of interest only to a minority of users or which are experimental: this is where the new "Advanced settings" pane is useful.
  • When you enabled "Advanced users" in the Settings pane, a cogs icon will appear next to that setting. Click this cogs icon to access those "hidden" advanced settings.
  • The UI of the advanced settings page is purposefully stern. Keep in mind that whatever settings you see in there may be experimental and could be removed at any time in the future.
  • Experimental advanced setting of interest: suspendTabsUntilReady (default to false), to prevent uBO from establishing any remote connection at launch before all filter lists/settings have been fully loaded (related issue #1327). How well it works will have to be evaluated by users.
  • WEBEXTENSIONS:
  • From now on, there will be a Firefox's WebExtension version of uBO (see uBlock0.webext.zip below, see "Temporary Installation in Firefox" on how to install on Firefox). Do not bother trying it out if you do not have Nightly 52.0a1 (2016-10-29) or later installed. Also, do not open issues here for the WebExtension version of uBO -- it is still at an experimental stage and there are things which are known to be missing in the API for uBO to fully function: see bugzilla 13099260.

  • Enhanced storage API infrastructure (this solves issues for Safari users where their preferences were being lost; it shouldn't affect Chrome/Firefox users)
  • Firefox now lets you block resources right from Web Inspector's network request log! (To try this out, just right click on an entry in the net-log). Thanks to @AlexVallat from the uBlock team for implementing this feature and what he's been doing to make uBlock awesome on Firefox.
  • UI changes and additions — you'll come across them: Dynamic filtering UI and Settings UI.
  • Note: Chrome users will notice that an extra permission is now asked for by uBlock (modifying privacy-related settings). The reason uBlock has that new permission is that it needs to modify the "Network Prediction" settings (which Chrome has enabled by default) in order to ensure more reliable blocking (there was an issue with Chrome "sneaking" certain requests so uBlock couldn't process them).
  • While uBlock modifies the network prediction setting (without reading its previous value) to ensure all requests are filtered correctly, uBlock never reads or modifies any of your other settings. Your uBlock preferences never leave your computer. We never see any of your data.

New in uBlock Origin 0.9.4.5 Beta 1 (May 15, 2015)

  • Some noteworthy new stuff to focus on:
  • Updated storage API infrastructure (this solves issues for Safari users where their preferences were being lost; it shouldn't affect Chrome/Firefox users)
  • Firefox now lets you block resources right from Web Inspector's network request log! (To try this out, just right click on an entry in the net-log). Thanks to @AlexVallat from the uBlock team for this and all the other work he's been doing to make uBlock awesome on Firefox.
  • UI changes and additions — you'll come across them as you use this beta build!
  • Dynamic filtering UI
  • Settings UI

  • UI, icons, and color scheme refinement.
  • Reliability improvements for domain-based blocking.
  • Stability enhancements for Firefox.
  • Cosmetic filtering right from Firefox's Web Inspector.

New in uBlock Origin 0.9.4.1 (Apr 14, 2015)

  • Chromium:
  • Popup blocker problem? (only on chrome)
  • Firefox:
  • this release is totaly junk
  • uBlock and uBlock0 could not run side-by-side properly because I had missed changing an id in the fork.

New in uBlock Origin 0.9.3.0 (Apr 4, 2015)

  • The uBlock project's main development responsibilities have been transferred to Chris Aljoudi (chrisaljoudi on GitHub).
  • PLEASE CONSIDER DONATING TO KEEP DEVELOPMENT POSSIBLE:
  • uBlock is still free and open-source, and will always be free and open-source. This does not change uBlock's manifesto or values in any way.
  • NEW:
  • Site-based switches
  • A switch to block all popups for a given site, regardless of filters
  • A switch to disable strict blocking (new mode, enabled by default)
  • This used to be supported by ABP a long-time ago: "full domain blocking"
  • FIREFOX:
  • Number of items in badge not updated when newtab url is about:blank
  • FIREFOX MOBILE:
  • Closing all tabs confuses ublock
  • CORE:
  • Can't find a way to allow popups
  • External script not blocked
  • This was a core issue but problem was manifesting only on Firefox.
  • Tooltip padding
  • CHN: EasyList China will cause the firefox hanging on some website
  • 'undefined' shows up in Dynamic filtering pane when popup blocker is enabled and a popup is blocked
  • The status of adblock warning removal list won't be stored in the backup file
  • Add lists from https://adblockplus.org/en/subscriptions
  • Selected domains no longer appears in the popup
  • Whitelist wildcard not working when url contains # as wildcard
  • Ability to blanket-block popups for a given site
  • See "site-based switches" above
  • Show "3rd-party filters list" info when category is collapsed
  • Chrome-scheme not showing up in popup
  • Unable to block browser take-over scripts in malware/phishing sites, or at least block redirects to such sites
  • See "site-based switches" above
  • Re. Strict Blocking - Should we do Domain blocking based on URL part itself?
  • Color for domains with both blocked and unblocked content is too similar
  • Problem with “element hiding” filters

New in uBlock Origin 0.9.2.3 (Mar 27, 2015)

  • Closed as fixed:
  • Selected domains no longer appears in the popup
  • EasyList FR was breaking uBlock, because of that weird filter: ||^$third-party, which makes no sense as per ABP filter syntax.

New in uBlock Origin 0.9.2.1 (Mar 23, 2015)

  • NOTES:
  • There is a version 0.9.2.2, not released here, because I feel it's not worth the storage space. The only difference with this version is this commit. This commit made it into the Opera store version as v 0.9.2.2.
  • CLOSED AS FIXEd:
  • µBlock -> uBlock.
  • In case you wonder: yes, I've decided to drop the µ in favor of u, because I have seen too much arguing about how it should be pronounced, etc.
  • 0.9.2.0 is now resizing each time you open it.
  • OTHER CHANGES:
  • CHROMIUM:
  • Various small changes to ensure Chromium passes all popup tests.
  • Due to limitations to the chrome API...
  • There is just no guarantee case 6, 7 will always work. The fix was to increase as much as possible the likelihood Chromium will succeed.
  • The only way I can make case 12 succeed on Chromium is by enabling uBlock for the behind-the-scene scope.
  • CORE:
  • Various small issues with element picker related to the new feature in 0.9.2.0.

New in uBlock Origin 0.9.2.0 RC 1 (Mar 21, 2015)

  • NEW:
  • Element picker: ability to point-and-click to create wildcard-based network filters
  • Brought about as a result of issue #1044: "non technical user [...] doesnt know how to [create wildcard-based filters]"
  • Roughly, if you click more than one image from one web page, uBlock will derive a network filter which will apply to all the clicked images.
  • Kind of difficult to put in words, so here are videos:
  • https://www.youtube.com/watch?v=kO0Mh-SAkHM
  • https://www.youtube.com/watch?v=WoFC3EJWg08
  • CLOSED AS FIXED:
  • CHROMIUM:
  • Blocking differrent kind of pop-ups
  • FIREFOX FOR ANDROID:
  • ublock options ui doesnt fit on screen
  • Blocking (off) when opening new tabs in Firefox from 3rd party apps
  • This also fixes:
  • Number of connected domains makes no sense
  • FIREFOX:
  • "Make use of context menu where appropriate" not enforced nor remembered
  • Empty buttons in addon options
  • Option buttons sometimes empty in addon properties
  • CORE:
  • uBlock slow/with delay blocking ads (banners) and elements on page twitch
  • Options-only filter is not working
  • abp:subscribe links on adblockplus.me do not work with new uBlock install
  • Cosmetic filter not working after refreshing the page
  • This was caused by an invalid cosmetic filter: custom filters from ABP were imported using plain cut & paste.
  • uBlock now support importing an ABP backup through the "Import and append" button in the "My filters" pane. This ensures proper import.
  • Additionally, uBlock will now discard invalid cosmetic filters when filter lists are compiled.

New in uBlock Origin 0.9.1.1 (Mar 16, 2015)

  • Closed as fixed:
  • Workaround #1001 for Fennec breaks Google Hangout extension

  • Image fails to load on github, when page is reloaded after whitelisting image cell
  • Safari:
  • Enable creating backups to work.
  • Does not restore properly from a backup created in Firefox, works fine in Firefox/Chrome.
  • Storage below quota as requested by uBlock; now uses proper storage API.

  • No indication of purging when clicking on the "Purge all caches" button
  • Double clicking to select word in "My rules" resets changes made
  • Global blocking stats lost when restoring/resetting settings
  • abp:subscribe, new automated import of ABP filters leads to undefined description

New in uBlock Origin 0.8.9.2 (Mar 5, 2015)

  • his version of µBlock, 0.8.9.2, is identical to 0.8.9.1 for every browser except Safari.
  • Changes (only 1!):
  • µBlock now implements a workaround older Safari versions don't crash. As tested, this version of µBlock is known to work on 6.1, 7.x and 8.x.
  • How does this workaround change µBlock on Safari 8.x?
  • This should not affect µBlock's functionality at all in Safari 8 and later.
  • How does this workaround change µBlock on Safari 7.x and older?
  • In those older versions of Safari, the only difference with the default configuration is that two of the pre-packaged filter lists (namely Peter's Lowe's Ad Server List and 'Malware Domains') will have to be downloaded instead.
  • By design, this download happens automatically by default, but you can always click manually trigger the download by clicking Update Now in µBlock's Preferences -> 3rd-party filters.
  • What was the problem?
  • What follows is written by me, µBlock's Safari-guy; it doesn't necessarily express the views of all project collaborators.
  • The problem was (and still is) a bug in Safari 7 and earlier. The bug still exists in those older versions of Safari, and any extension that may happen to trigger it will cause those crashes.
  • Hopefully Apple will push a fix to those older versions of Safari (otherwise, some other extension and its users may encounter this in the future).
  • If you're curious about the bug, read on.
  • Specifics of bug
  • µBlock ships pre-packaged with copies of the filter lists it supports — that way, it has something to use for the lists enabled by default right away without having to download them from the servers first.
  • Those pre-packaged filter list files are named similarly to what their maintainers named them. For instance, EasyPrivacy can be accessed at easylist-downloads.adblockplus.org/easyprivacy.txt, so the filename for the pre-packaged version is easyprivacy.txt.
  • When µBlock is installed and it launches, it loads those files using simple XHR requests. Safari, like most browsers, gives us a way to do that: you use safari.extension.baseURI followed by the path to your file, and voilà, you can load a file you packaged with your extension.
  • This indeed works well with most things, including our example above (easyprivacy.txt). In fact, it seems like since Safari 8.0, it works perfectly. No problems whatsoever.
  • But Safari 7.x crashes miserably. This is already odd: a JavaScript program shouldn't be able to crash your whole browser no matter what.
  • After doing much investigation via VNC on a virtual machine that's actually running Mavericks, I found the problem. Two of the default filter lists:
  • those two lists were pre-packaged in files that shipped with µBlock: justdomains and serverlist. No .txt suffix.
  • Safari 7.x crashes if you try to load a file from your package whose name happens not to have an 'extension'.
  • easylist.txt? Dandy. justdomains? Boom.
  • Correct: it's not just a mere stray exception thrown, the whole browser crashes.
  • I think it was fair to conclude this was a browser bug. It's not due to negligence on µBlock's part.
  • With the obscurity and nature of this bug considered, this problem with µBlock for Safari was the result of an unfortunate incidental set of circumstances, unavoidable without the hindsight we have today.
  • As the Safari maintainer (just personally), I hope you understand. Enjoy µBloc

  • Button label with number of blocked requests switches to superscript with red background
  • Core:
  • [Regression] Left-, right-anchored network filters with one wildcard broken in 0.8.9.0

New in uBlock Origin 0.8.9.0 (Feb 28, 2015)

  • Reminder:
  • Chromium (or browsers based on) still suffer from that ugly bug which causes a big chunk of memory leak each time a user opens the popup UI of an extension. Therefore, the more you use the popup UI in Chromium, the larger the memory footprint of µBlock (or any extension really) will grow. I've already seen feedback like "doesn't have a µ memory footprint at all for me. >250MB" (for µMatrix). This is important to keep this Chromium memory leak bug in mind if you make use of dynamic filtering, as this feature requires frequent access to the popup UI.
  • Closed as fixed:
  • Chrome store feedback: "any.gs/linkbucks ads"
  • Still need to be fixed for Firefox
  • Placeholders of blocked images not being shown
  • Element picker - have to hover to see buttons?
  • Dynamic Filtering: Can't use noop or allow rule for image type based on destination-hostname
  • It still not allowed, but the non-supported rules will be discarded now
  • [Firefox] Slow startup when compared to AdBlock Plus fixing
  • Clarification: Adblock Plus delays the loading of filters at launch, uBlock does not delay the loading of filters, therefore ABP just appeared faster to load, while in reality it was not if one considers that "startup" means "fully loaded and ready"
  • Despite this difference, work has been done to further improve load speed
  • Some charts

New in uBlock Origin 0.8.8.5 Dev 3 (Feb 26, 2015)

  • Closed as fixed:
  • Chrome store feedback: "any.gs/linkbucks ads"
  • Still need to be fixed for Firefox
  • Placeholders of blocked images not being shown
  • Element picker - have to hover to see buttons?
  • Dynamic Filtering: Can't use noop or allow rule for image type based on destination-hostname
  • It still not allowed, but the non-supported rules will be discarded now
  • [Firefox] Slow startup when compared to AdBlock Plus fixing
  • Clarification: Adblock Plus delays the loading of filters at launch, uBlock does not delay the loading of filters, therefore ABP just appeared faster to load, while in reality it was not if one considers that "startup" means "fully loaded and ready"
  • Despite this difference, work has been done to further improve load speed
  • Some charts (will fill in explanations as time allow)

New in uBlock Origin 0.8.8.4 (Feb 26, 2015)

  • Closed as fixed:
  • [Safari] YouTube ads not being blocked and cannot be skipped.
  • The fix for this includes major improvements to Safari blocking — added coverage of programmatic Image requests and fuller coverage of XMLHttpRequest interception.
  • [Safari] increase extension storage quota to err on the safe side.

New in uBlock Origin 0.8.8.5 Dev 2 (Feb 25, 2015)

  • this fixes #828

New in uBlock Origin 0.8.8.3 (Feb 23, 2015)

  • Closed as fixed:
  • Adultswim Player Doesn't Work
  • In some cases, the code to work around Chromium bug 410382 failed to do its workaround job.
  • Hence this only affected Chromium-based browsers.

New in uBlock Origin 0.8.8.2 (Feb 20, 2015)

  • Safari:
  • Toolbar icon now looks different on whitelisted pages.
  • Closed as fixed:
  • Sites loading as text only
  • This could happens sometimes when network requests had to be evaluated while uBlock loaded its filter lists (at launch or during an update).
  • Ability to collapse dynamic filtering pane such that only root domains show
  • Click the all cell at the top to reveal/hide subdomains
  • make textarea in My filters tab 100% wide

New in uBlock Origin 0.8.8.2 Pre 0 (Feb 17, 2015)

  • New:
  • Albanian translation thanks to bogdole.
  • Supported in Firefox, not supported in Chromium or Safari unfortunately.
  • Changes:
  • Dynamic filtering pane:
  • You can now collapse/expand the all subdomains: click on the all cell.

New in uBlock Origin 0.8.8.1 (Feb 16, 2015)

  • Emergency fix:
  • [Core] Loading local copy of an un-cached asset was broken
  • Regression bug from fix to issue #376
  • This affected Safari only

New in uBlock Origin 0.8.8.0 (Feb 16, 2015)

  • CHANGES & ENHANCEMENTS:
  • Safari:
  • Important (though minor) improvements in request capturing(d2cc20e)
  • Bonus: out-of-the-box support for HTML5 twitch.tv (some users may need to disable Flash to get the HTML5 player)
  • CORE:
  • All dynamic rules are temporary by default: Click the padlock if you want to persist the ruleset for a specific web site.
  • The padlock will be visible if and only if there is at least one temporary rule in the pane
  • This is really the optimal way to use dynamic filtering, as using this feature is often a matter of trial and error
  • This prevents ruleset pollution: your ruleset will be only those which you will have explicitly persisted
  • If you Ctrl-click to set/unset a rule, it will be immediately persisted (command ⌘-click on Mac)
  • µBlock's power button's color is now 450nm-blue-LED: green could lead to confusion given that in the dynamic filtering pane, green is used to denote that network requests won't be blocked.
  • The assets auto-updater has been rewritten, to work in a more gentle and discrete way
  • Assets which need to be updated will be fetch one by one in the background, with a good delay between each fetch (this prevents large peak in memory and network bandwidth usage)
  • Once all assets have been updated, they will then all be reloaded using their locally cached copies
  • The optimal way to update assets in µBlock is to let auto-update do the job: it is more gentle on resources locally and also more gentle to remote servers
  • CLOSED AS FIXED:
  • Firefox:
  • [Firefox] Some embedded youtube videos do not work without a global noop rule for youtube
  • [Firefox] Popup issues
  • Safari:
  • [Safari] Blob: type is included in 3rd party list, even though the path is first party
  • [Safari] can't access ublock prefs on fav page
  • Core:
  • Could not remove pcbeta's ads
  • Domains Connected Count is incorrect
  • Malware domains long-lived no longer necessary?
  • Support importing RequestPolicy export files
  • Reload button on the popup isn't disappearing on internal pages

New in uBlock Origin 0.8.7.1 Pre 6 (Feb 14, 2015)

  • Reminder: Chromium (or browsers based on) still suffer from that ugly bug which causes a big chunk of memory leak each time a user opens the popup UI of an extension. Therefore, the more you use the popup UI in Chromium, the larger the memory footprint of µBlock (or any extension really) will grow. I've already seen feedback like "doesn't have a µ memory footprint at all for me. >250MB" (for µMatrix).
  • This is important to keep this Chromium memory leak bug in mind if you make use of dynamic filtering, as this feature requires frequent access to the popup UI.
  • Changes & Enhancements
  • The assets auto-updater has been rewritten, to work in a more gentle and discrete way
  • Assets which need to be updated will be fetch one by one in the background, with a good delay between each fetch (this prevents large peak in memory and network bandwidth usage)
  • Once all assets have been updated, they will then all be reloaded using their locally cached copies
  • The optimal way to update assets in µBlock is to let auto-update do the job: it is more gentle on resources locally and also more gentle to remote servers
  • Closed as fixed:
  • Domains Connected Count is incorrect
  • Malware domains long-lived no longer necessary?
  • Support importing RequestPolicy export files
  • Reload button on the popup isn't disappearing on internal pages
  • Power button should not be green
  • [Safari] Blob: type is included in 3rd party list, even though the path is first party
  • Make a preference temporary for just this session
  • [Firefox] Popup issues
  • [Safari] can't access ublock prefs on fav page
  • When updating, wait for update to complete before discarding memory used by previous filters

New in uBlock Origin 0.8.7.1 Pre 5 (Feb 13, 2015)

  • Changes & Enhancements:
  • All dynamic rules are temporary by default: Click the padlock if you want to persist the ruleset for a specific web site.
  • The padlock will be visible if and only if there is at least one temporary rule in the pane
  • This is really the optimal way to use dynamic filtering, as using this feature is often a matter of trial and error
  • This prevents ruleset pollution: your ruleset will be only those which you will have explicitly persisted
  • If you -click to set/unset a rule, it will be immediately persisted (command ⌘-click on Mac)
  • µBlock's power button's color is now 450nm-blue-LED: green could lead to confusion given that in the dynamic filtering pane, green is used to denote that network requests won't be blocked.
  • [Safari]: important (though minor) improvements in request capturing
  • Bonus: out-of-the-box support for HTML5 twitch.tv (some users may need to disable Flash to get the HTML5 player)

New in uBlock Origin 0.8.6.0 (Feb 2, 2015)

  • NEW:
  • Bulgarian translation by antonpenev, avp3000, ecogiko, vladev
  • Found out today that work on this translation had been started since late December and I had missed it: sorry about this
  • Korean translation by delightbot
  • Latvian translation by 7nolans, spitaligais
  • Persian translation by omid3098
  • CLOSED AS FIXED:
  • Chromium:
  • [Chromium] Sometimes web pages may not be cleaned up properly after launch
  • Somehow nobody complained of this regression bug, which probably manifested not that often when µBlock loaded from a selfie
  • [Chromium] Chromium bypassing uBlock through behind-the-scene requests
  • [Working on documentation: for now look into request logger drop down list]
  • Behind-the-scene requests can only be filtered if "advanced user" mode is enabled -- though you can examine them in the request logger regardless of mode
  • Firefox:
  • [Firefox] Popup blocker incorrectly closes user clicked window
  • Safari:
  • [Safari] Fix YouTube ClickToPlugin conflict
  • [Safari] Big fixes to Safari vAPI stuff
  • [Safari] Turning off uBlock for domain doesn't make the site load properly, disabling uBlock does
  • [Safari] Safari Extension Gallery
  • Core:
  • [Core] Element picker (nth-child usage)
  • [Core] host name not displayed in dynamic filtering frame, when inline-scripting is active..
  • [Core] dynamic-net-filtering.js length typos
  • [Core] Filters with multiple negated request types
  • [Core] Support regular expression-based network filters
  • I just got tired of the suspiciously often-repeated fallacy that uBlock was more efficient because it didn't support regular expression-based filters (only 15 of them in all of EasyList...)
  • µBlock-specific documentation for regex-based filters
  • [Core] Romanian list
  • [Core] Move µBlock.transposeType() to Chromium's platform-specific code
  • [Core] Feature Request: allow µBlock to run on chrome:// urls
  • µBlock is now active regardless of what URL is present in the address bar. For non-HTTP-like URLs, µBlock will create and use a synthetic URL internally, so that these non-standard URLs (about:config, chrome://settings, file:///..., etc.) can be whitelisted and have their own dynamic filtering rules.
  • As far as I can tell this is fully functional for Chromium. There is probably platform-specific code in need of work to have the same feature for Firefox, Safari.
  • NOTES:
  • Lots of work from volunteer translators imported from Crowdin
