How to Block Facebook Beacon

Steps

1. Install the Firefox browser if you do not already have it.

   Install the BlockSite extension from the Mozilla website. You can also use the popular Adblock plus extensions.
   
   
   
   • Scroll down the page and click on the green Install Now button. Firefox may try to block the installation; if so you will see a yellow bar appear at top of your browser window with text "Firefox prevented this site (addons.mozilla.org) from asking you to install software on your computer." If you see this message, click on the Edit Options... button on the right side of the yellow bar and a small pop-out window will appear.
     
     
     
   • Click on the "Allow" button on the pop-out window to add this site to the list of sites you permit to install addons.
     
   • Close the pop out window by clicking on the red circle in the upper left corner (Mac OS X) or the red "X" at the top right (Microsoft Windows).
   • Click on the green Install Now button on the Mozilla Add-ons web page a second time. Another small window will appear.
   • Click on the blue button in the new window to install the BlockSite extension.
     
   • Restart Firefox once this extension has been installed to complete the process and enable BlockSite.
