There has been a lot of talk about privacy and especially how to block a referer being sent to a web site. Well there is a extension at Firefox called Refcontrol you can download. Very easy to use and configure. 1.) You can control referer by site to site bases. 2.) Or set to block by default 3.) Or List a false web by default so as the website will log it in and won't really know where you came from.....this is really a jewel to have.....enjoy. For those that have firefox installed....under "privacy and Security" you can find this extension.
