Twitter overload? Don't despair. I introduced you to Tweet Deck recently as a way to help organize your flock into groups, but unfortunately, as an Adobe Air application, I've heard people say that it slows down their computers.
The faster I can update my social network statuses, the better, especially for the rapid-fire pace of Twitter. There's already a Firefox download for making Twitter updates from your address bar, but throw the word "fox" into it, and I'm a sucker (case in point).
TwitterFox works seamlessly from your Firefox browser window (and it's only for Firefox, if that wasn't obvious enough) to bring you the up-to-the-minute updates of your friends.
