Note: Facebook asks us to clarify that cookies specific to a user's account are deleted when they log out of Facebook, so the company does not receive personally identifiable cookie information when logged-out users browse the web. Other cookies associated with the web browser remain active after log-out.
Facebook tracks you -- even if you're not logged in. Its cookies don't expire when you sign out, but are altered to allow the site to keep tabs on your web activity. Here's how to stop Facebook stalking you on different browsers. TC
Go to Preferences, then Privacy. Click on "Remove individual cookies", underlined at the bottom of the tab. Enter "Facebook" in the search bar -- you'll see all the cookies used by Facebook.
Select these and hit "Remove cookies".
Chrome
Go to Preferences, then select "Under the Hood" on the left-hand tab. Under "Privacy", go to "Content settings". Go to "Cookie and data exceptions" and add "facebook.com".
Internet Explorer 9IE9 doesn't let you be specific about exactly which third-party cookies you can block. So to ban all of them in one swoop, go to "Tools" (the cog in the right-hand corner), "Internet options", "Privacy", then "Advanced". Choose to block or receive a prompt when someone tries to track your web movements instead.
