Facebook Beacon BlockerJanuary 26, 2009 – 10:07 AM
Facebook Beacon has been heavily criticized by privacy advocates since its introduction. The main point of criticism is that users cannot opt out completely. While they can prevent that information from the 44 partner sites will be published publicly and accessible by friends they cannot prevent Facebook from receiving the data in first place. There is no opt out of the system other than blocking the scripts from being executed.
Facebook Beacon Blocker is a Firefox add-on that will block the Facebook Beacon service from collecting and sending information about the user to Facebook. It basically blocks the script from being executed on the partner sites which is all it takes to turn the service off completely.
