Username or EmailPassword
Nothing against Firefox, but I'm still finding Mozilla to be a wee bit more robust than anything else. (I've seen some sites that Moz handles fine that whack Firefox. It is a 1.0 release after all... Linux version's mailto: link not yet working for example). You also get email, IRC and an HTML editor with Moz.
I'm expecting Firefox to rule soon, but I'm just kind of wondering why Mozilla never got this kind of attention. And in the linux /BSD world it was our standard browser for years, no? The windows flavour is still an excellect candidate IMHO
