Lightbeam for Firefox!

Ghostery sees the invisible web - tags, web bugs, pixels and beacons. Ghostery tracks the trackers and gives you a roll-call of the ad networks, behavioral data providers, web publishers, and other companies interested in your activity. After showing you who's tracking you, Ghostery also gives you a chance to learn more about each company it identifies. How they describe themselves, a link to their privacy policies, and a sampling of pages where we've found them are just a click away.Ghostery allows you to block scripts from companies that you don't trust, delete local shared objects, and even block images andiframes. Ghostery puts your web privacy back in your hands. Ghostery has different builds for the different browsers. »

TrackMeNot is a lightweight browser extension that helps protect web searchers from surveillance and data-profiling by search engines. It does so not by means of concealment or encryption (i.e. covering one's tracks), but instead, paradoxically, by the opposite strategy: noise and obfuscation. With TrackMeNot, actual web searches, lost in a cloud of false leads, are essentially hidden in plain view. User-installed TrackMeNot works with the Firefox Browser and popular search engines (AOL, Yahoo!, Google, and Bing) and requires no 3rd-party servers or services. »
