importing bookmarks to firefox

thanks in advance

Firefox is quite possibly the greatest browser I've ever used. Those of you stupid enough to enjoy Microsoft's shitfest IE experience, please continue to do so, as it thins the ranks of the Firefox development community of idiots.

And please, stop using FailFux instead of Firefox, it's damned retarded, and ranks you dickholes among people who use M$, Macintrash, Crapple, and WinDoze.

Your browser sucks, you suck, shut up.
