Track Me Not

“TrackMeNot is a browser extension that protects web-searchers
against surveillance and
data-profiling. It does so not by means of concealment or encryption (i.e.
covering one’s trail), 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, e.g. AOL, Yahoo!, Google, and MSN. “
