I use the twitterfox extension for FF.
It's not gorgeous, but it's not half bad, either--very usable and good looking, cross-platform and decently featured. And unobtrusive--rather than sit the in the sidebar, it only occupies a tiny icon in the status bar, then opens to an IM-window size when you click it.
I used twitux for a while, but went back to twitterfox for UI reasons. Haven't tried the others.
