Ghostery is a web service that scans the web pages you visit to find web bugs. Ghostery reveals who is tracking your views of a page on the Internet according to a common but under-examined method: web bugs. With Ghostery, you are able to detect more than 115 web bugs, ad networks and trackers.

Web bugs are used to track your behavior on the web in order to help the sites you visit to understand their own audiences and to allow advertisers to target ads at you.

Get Ghostery for Firefox.
