Extendable through user scripts
Greasemonkey is practically a user scripts manager that helps you take control over the way in which you access the web. In other words, Greasemonkey is pretty much useless without any scripts installed.
Fortunately, user scrips are available all over the Internet and the Greasemonkey community constantly publishes useful new scripts. The great thing about Greasemonkey is that you can quickly and effortlessly install a user script with just a couple of mouse clicks.
Thanks to Greasemonkey, you can use the desired user scripts to adjust the behavior of a page, change Gmail’s appearance for example or remove advertisements from your favorite pages. Hence, Greasemonkey allows you to improve your browsing experience and the way in which you interact with web pages.
The amount of available user scrips is impressive and even more scrips are constantly added every day. On top of that, you can create your own script that can run with Greasemonkey.
Unfortunately, the use of user-created code might raise some security issues. As a result, you should install user scripts from popular webpages and go for the scripts that already have a large number of installs.
On the other hand, the installation of a script can be easily performed via a link on a web page or by dragging a local file into your browser window. You can also use the File menu and the Open File dialog window to open user.js scripts. From Greasemonkey’s Options menu you can quickly access the script editor if you want to write your own script.
