Personally I think the importance/usage of Firefox is somewhat overstated/over-estimated by this little write up.
I've been using Firefox on my PC's since it's inception and absolutely love it so TimberWolf coming to my favourite OS is of the upmost importance to me as an AmigaOS user today :drink:
(oh & of course glUAE which allows me to run all my favourite classic 68k apps/games seamlessly under OS4.x:))
