While it technically works, it makes everything, particularly Youtube, MUCH slower. You click pause, and it takes 3-5- seconds before it actually does it

Just a reminder of how much FB is up in yer bizniz during the day.

This extension stops Facebook from tracking you as you surf the web in Firefox; however, this extension does not prevent facebook from tracking you to other sites when clicking on a link posted on the facebook website. The Facebook link-shimming server (l.facebook.com - that's a lowercase L not a captial I) circumvents this container by injecting new copies of Facebook cookies and locally stored objects (LSO) into the newly opened container, tab, window, or even a completely different browser prior to being directed to the link you think you are going to directly.

Installed it and for some reason images in Twitter don't show. Disable and refresh and they show again. Must be affecting it somehow.

yep, same as a few people, i can't log into facebook any more. not seen any support available for this issue either.
