For once Firefox has been behind. They're one of the last to get HTML5 and private browsing (Only beating Opera).

I'm not really sure what that location thing does, but anyway. However, I'm wondering how that font thing would work, I mean fonts are executable programs, they could easily be Trojans. But if they somehow (IDK how) made it safe, it would be a good feature.

And yeah, it's been out for over a week. :P
