PrivacyPro

PrivacyPro is completely Free, advanced privacy enhancing extension which stops search engines from collecting data via Referrer and other tracking methods.

The extension will hide your referrer while visiting Google, Yahoo or Bing, thus, they will not know the website you came from. Additionally, it will truncate URLs so there are no tracking parameters passed through the search engine.
