QuickJava by Doug G

Rated 5 out of 5 stars 203 reviews

263,174 users

Allows quick enable and disable of Java, Javascript, Cookies, Image Animations, Flash, Silverlight, Images, Stylesheets and Proxy from the Toolbar. This is great for increasing security or decreasing bandwidth.
Collector's Note I think this is much better than things like NoScripts. Much less cluttered, much less time wasting and much more simpler to use. The only negative - it takes space of 5 buttons on the addon bar(although the buttons are beautiful, I must say). If you want only one button to toggle all plugins, use the Pluggin toggler.

Tab Mix Plus by onemen, Gary Reyes

Rated 4 out of 5 stars 2,599 reviews

800,115 users

Tab Mix Plus enhances Firefox's tab browsing capabilities. It includes such features as duplicating tabs, controlling tab focus, tab clicking options, undo closed tabs and windows, plus much more. It also includes a full-featured session manager.
Collector's Note An absolutely indispensable addon. A few words of note : (A). You can also use Tab Mix Plus's Session manager instead of the separate addon 'Session Manager'. But the advantages of Session manager are 1. More powerful, Stores more sessions 2. If you also have the addon "Session Manager Export tool" then you can export and save your sessions. (B) Tab Mix Plus can be made even more powerful if you use it alongwith two more addons - Multiple Tab Handler and Tab Groups Manager. ............................... I am using Firefox 18 at the time of writing. And these days I prefer Tab Utilities over Tab Mix Plus because it allows me to stack Tabs like Opera. Tab Mix Plus so far does not have this function. Also I use the addon Tab Kit 2nd Edition which plays better with TU than with TMP. The advantages of Tab Mix Plus are that although it offers fewer functions than Tab utilities, those functions are solidly built and complete. Also most developers who make tab related addons ensure that their addons are compatible with Tab Mix Plus, so TMP works well with most other Tab related addons (except Tab Kit 2nd Edition which works with Tab Utilities better because both were developed by the same guy)
