Mozilla has a petition asking Facebook to stop tracking people's browsing off the site unless they opt in to it. Frankly I think the solution is to remove the ability to track people across sites from the web entirely, but I signed the petition anyway. Facebook has taken a huge hit to their reputation, so now is a good time to be putting pressure on them to change their ways.
@seanl @ebel Presuming you are not being sarcastic, the CEO noted in an interview there were parts they wouldn't enforce worldwide. I wouldn't ever bet on Facebook doing the right thing. ^_^
