Nate Weiner over at the Idea Shower has been playing around with Facebook’s advertising platform and reports the following:
There are several simple steps to be taken in order to block the Beacon. First of all, users need to download and install the BlockSite plugin for Firefox, available here. After the browser restart, users must select ‘Add-ons’ from the Tools menu, click the ‘Options’ button on the BlockSite extension and “http://*facebook.com/beacon/*” into the input box. The job will be done two clicked “Ok” buttons later.
