  • HDR video is now supported in Waterfox on Mac—starting with YouTube! Waterfox users on macOS 11+ (with HDR-compatible screens) can enjoy higher-fidelity video content. No need to manually flip any preferences to turn HDR video support on—just make sure battery preferences are NOT set to “optimize video streaming while on battery”.

As part of this, the built-in content blocking will automatically block third-party scripts, images, and other content from being loaded from cross-site tracking companies reported by Disconnect.
  • Introducing a new referrer tracking protection in Strict Tracking Protection and Private Browsing. This feature prevents sites from unknowingly leaking private information to trackers.
  • RLBox—a new technology that hardens Waterfox against potential security vulnerabilities in third-party libraries—is now enabled on all platforms.

  • To better protect all Waterfox users against side-channel attacks, such as Spectre, Gecko introduced Site Isolation.
  • Waterfox supports the new Snap Layouts menus when running on Windows 11.

  • Video overlay is enabled on Windows for Intel GPUs, reducing power usage during video playback.

New in Waterfox 56.0 (Dec 1, 2017)

  • IMPORTANT! WATERFOX NOW USES ITS OWN PROFILE LOCATION:
  • Waterfox now uses its own profile directory. If you have updated from an automatic update, you will get a prompt to import your data to this new location after restarting the browser post update.
  • As much of your data will try to be kept as possible. Location on macOS: ~/Library/Application Support/Waterfox.
  • If you use a different than default location for Firefox, you should be able to just update the profile.ini in the new Waterfox profile location to carry on using that location.
  • WHAT’S NEW IN WATERFOX 56.0:
  • Waterfox will now remain at 56 for the time being, following the security releases of 59 ESR until it becomes End of Line (Q1 2019). In the meanwhile, a “new” browser will be developed to follow the ethos of Waterfox of customisation and choice, while staying up to do date with the rapidly evolving browser landscape.
  • Based on Firefox 56.0.2 release.
  • Fixed GUI rendering issues on macOS High Sierra.
  • Fixed search suggestions not appearing.
  • Enabled e10s by default, some add-ons that aren’t marked as compatible may cause unexpected behaviour.
  • Cookie Prompt has been re-implemented thanks to Savarese.Org: Firefox used to allow you to be notified every time a Web site attempted to set a cookie. You could decide to accept or reject the cookie as well as specify the cookie lifetime and whether to use your choice for all cookies from the Web site, thereby updating your cookie preferences.
