The first and only download manager/accelerator built inside Firefox!
Squared tabs, appmenu, add-on bar, small button view and many more 'old' features for Firefox 29+ (Windows / MacOSX / Linux).
All builds & changelogs on versions page!
Fix the web. Gets rid of a site's cookies and LocalStorage as soon as you close its tabs. Protects against trackers and zombie-cookies. Trustworthy services can be whitelisted.
The greatest user script engine on the Internet (a fork of Greasemonkey).
Monitors web pages for updates. Useful for websites that don't provide Atom or RSS feeds.
