@KennyR:
Bloated browsers.. well maybe they are, on the other hand, how much effort do you want to put in to optimising. I think Mozilla is still too slow for my liking (I'm using moz. firebird 0.6 on Debian also :-) ) but on the other hand how much time do you want the authors to "waste" in making tighter code, which could end up being potentially less maintainable, more bugs, less hackable, etc.
I think firebird is an *ok* compromise.
