Restyle the web with Stylish, a user styles manager. Stylish lets you easily install themes and skins for Google, Facebook, YouTube, Tumblr, and many, many other sites. You can even customize Firefox and other programs themselves.
Monitors web pages for updates. Useful for websites that don't provide Atom or RSS feeds.
Start/stop GIF animations through a keyboard shortcut or by clicking them. You can also restart animations from the beginning, or disable animations by default.

Enables Adobe Acrobat-style grab and drag scrolling, Flick gestures, and Momentum scrolling in Firefox. Useful for (older) pen or touchscreen-based devices for which these gestures are not natively supported. Not useful on Windows 8 touch devices.
