I use Adblock which is free. It is available for Chrome, Internet Exploder (not a typo - lol), and Firefox. Works great for me! If this CNET version doesn't fit the browser you use, you may have to Google to find the version for the different browser.

I've been using Ad Block with FireFox since it was available as a plugin. How do you tell if FB and Twit is even running, I don't see any Icons for them?
