Most weblogs and a lot of other websites have started to use Facebook scripts on their Internet pages.
The most prominent script is Facebook Like, which displays a like button and the "likes" on the web page. Likes are basically votes for that page by Facebook users.
There are other Facebook scripts, like recommendations for instance, or the dreaded Facebook wall of profile photos that can appear on websites as well.
Update: Facebook Blocker has not been updated since 2011. The project appears dead, and you may run into issues installing the extension, or using it. We suggest you use an up to date extension like uBlock Origin instead, and install the social media list for it once you have installed it to benefit from similar functionality.
Facebook Blocker is a web browser extension that blocks those Facebook plugins and scripts from being loaded on third party websites. The scripts will still work fine on Facebook. Scripts that are integrated directly and by the use of iFrames are blocked. A positive side effect is that it will also block Facebook from tracking the browsing history much like tracking cookies do. (It needs to be noted that it is not entirely clear if and how Facebook tracks users through their scripts)
Facebook Connect, which is a service by Facebook to offer sign-in to services using their Facebook account, will continue to work on third party sites as well.
The Facebook Blocker extension removes the Facebook script from the website so that it is not executed or visible anymore. This is an automated process. The user basically needs to install the extension and keep it activated for as long as Facebook content's should be blocked in the web browser.
Facebook Blocker is available for Google Chrome, Safari and Mozilla Firefox. Downloads are provided directly on the project homepage over at Webgraph.
Users may also experience that sites who have implemented Facebook scripts load considerably faster after the installation of the extension. This can be attributed to the fact that less items need to be downloaded to render the page.
