Bloat, bloat, bloat, bloat.
I'm still using FF 2.0.0.20 on both my G4 tower and G4 iBook, as FF 3.0 was absolutely dog-slow -- not to mention that there's no way to get rid of those goddamn' thumbnail site icons in the Bookmarks menu which, I'm quite sure, is what's slowing things down in FF 2.x and is what almost always sent FF down in flames in early versions of 2.x and 3.x.
I tried a later version of FF 3.x on my iBook and, while it was able to access the Bookmarks menu without crashing -- which is what almost invariably happened as it tried to load all those goddamn' icons next to the site names -- I still had to wait several seconds while FF grunted and groaned as the Bookmarks menu crawled down the screen.
I got rid of FF 3.x pronto, and have gone back to 2.0.0.20, which can at least load that needlessly icon-loaded Bookmarks menu without crapping its drawers.
FF is still my main browser, but I've found myself occasionally tinkering with Opera while waiting for something better as, sadly, Mozilla seems determined to send FF down the road to ruin.
