I was looking at a friend's picture, then tried to click on one of the profiles of a commenter and got a Firefox error saying it didn't know how to handle the Facebook:// protocol. So when I hovered my mouse over the profile it shows the link as "fb://profile/####" and all of the others in the same comment were normal http:// links to their profiles. Anyone know why that one person has a Facebook:// link and the others have http://?


Facebook has been using something they put together as FBML. Their version of HTML, internet programming language. It is being removed and reverting to HTML by June 1st. Facebook is glitchy on a good day. You can read more about it here
