Covering Your Tracks in Firefox
Firefox users looking for a little more control over the privacy of their Web browsing habits should check out a handy add-on called "RefControl," a Firefox extension that lets you decide which sites should be allowed to see your most recent browsing history.
When you visit a Web site, the people who run that site can see by looking at their traffic logs the name and Internet address of the site you were at directly before visiting their site, also known as the "referrer" link.
Using RefControl, Firefox users can block all referrers, or block referrers for all sites except those included on your personal exclusion list. RefControl users can even set a fake referrer for all or specific sites that includes a custom message (e.g., "NoReferrerForYou"), a sentiment that will show up in the visited Web site's logs.
