QuickJava by Doug G

Rated 5 out of 5 stars 210 reviews

240,366 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.
