https://addons.mozilla.org/en-US/firefox/addon/collusion/Ladies and gents, here is an experimental extension (not plugin) for Firefox used to visually graph which third parties are watching you masturbate surf the web. Altered host files and intercepting proxies such as Privoxy will cause inaccurate results. This extension is still experimental and hopefully does not track you.
This extension is being billed as a Mozilla vs Google issue. Also not compatible with FireFox 9.X.X or older. Nor does it work with all websites, I have only seen success when browsing news sites.
