Facebook has received plenty of criticism for its Beacon service. If you aren't familiar with Beacon, it allows Facebook to receive information from partner sites that can be used a couple of ways. First, it lets you share your activities on other website with your Facebook friends. Second, it allows Facebook to keeps tabs on you and generate a robust targeted advertising profile.

Not too excited about that? If you're a Firefox user, you might want to install the Facebook Beacon Blocker addon. It does what it says, and it's probably the simplest option available. It's currently experimental, so you'll need to log in to the addons site to install it.

There are other ways to do this - like blacklisting with the Block Site addon or your own proxy server, or, as suggested by gHacks, blocking facebook.com with NoScript.
