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. »

DoNotTrackMe is the new and improved DoNotTrackPlus. Now with more tracker blocking power, stop identity thieves, advertisers, social networks, and spammers from tracking you.

ShareMeNot is designed to prevent third-party buttons (such as the Facebook “Like” button or the Twitter “tweet” button) embedded by sites across the Internet from tracking you until you actually interact with them.

Sets permanent opt-out cookies to stop behavioral advertising for 100+ different advertising networks, including Google, Yahoo, Microsoft, all members of the Network Advertising Initiative, and many other companies.

Social networking sites like Facebook, Google+, and Twitter can track your visits to any web page that uses the familiar "Like", "Follow", or "+1" buttons, even if you do not actually click these buttons. The Priv3 Firefox extension lets you remain logged in to the social networking sites you use and still browse the web, knowing that those third-party sites only learn where you go on the web when you want them to.
