Even if you're happy with your Facebook privacy settings, you might find the relentless spread of its 'Like' button across the Internet annoying. Using Firefox extension AdBlock, it's pretty easy to get rid of that nuisance.
Blog The Gay Bar details how a couple of additions to your AdBlock rules can vanish the Like button from view. If you're especially privacy-conscious, the site also notes how you can use AdBlock to restrict Facebook's activities entirely to its own domain. Of course, at that point, making a strategic retreat from Facebook without sacrificing its benefits might make more sense. Thanks Nikhil!
