Greasemonkey is a Firefox extension that lets you add bits of DHTML (user scripts) to any Web page to change its behavior. In much the same way that user CSS lets you take control of a Web page's style, user scripts let you easily control any aspect of a Web page's design or interaction. For example you could make sure all URLs displayed in the browser are clickable links, improve the usability of a site you frequent, route around common and annoying Web site bugs, or use the Coral content network selectively.

Adblock Plus allows you to regain control of the internet and view the web the way you want to. The add-on is supported by over forty filter subscriptions in dozens of languages which automatically configure it for purposes ranging from removing online advertising to blocking all known malware domains.

Adblock Plus also allows you to customize your filters with the assistance of a variety of useful features, including a context option for images, a block tab for Flash and Java objects, and a list of blockable items to remove scripts and stylesheets.

While similar extensions exist for Firefox, none has the reputation of this one, which will also work in Thunderbird and SeaMonkey.
