Firefox Extension: Twitterfox

Twitterfox is a handy little Firefox Extension for all users of Twitter. It keeps you up to date with your friends twitters, and gives you a nice quick interface for posting. It takes up a tiny piece of real estate on your status bar (an issue if like me you have a lot of extensions that place things there, I have run out of space on some of my installs, and Firefox gets a bit ugly when that happens).
What is also worth mentioning is that it is really nicely designed, the alerts and interface for reading/posting twitters is tiny and well done. I suspect that the style may well end up influencing other similar extensions, as it is the way to do it. I’d love similar for status updates to Facebook for instance.
