I have no need for or interest in Facebook. I don't want to see any Facebook icons or comment streams or messengers. I employ a melange of techniques to block Facebook shit from taking residence in my computer. But this is appearing to become more and more difficult with every passing day.
I dislike Facebook too.
Social API is not tied to Facebook. Any service (including Facebook can use it).
Firefox 17 does not come with any Facebook icons, or Facebook ties. It just comes with Social API that can be used by social networking websites.
To site in question request permission to use Social API, and then the user allows or disallows integration.
