Ghostery (for Firefox)

Ghostery is your window into the invisible web - tags, web bugs, pixels, and beacons that are included on web pages in order to get an idea of your online behavior. Ghostery tracks over 1,000 trackers and gives you a roll-call of the ad networks, behavioral data providers, web publishers, and other companies interested in your activity.
