FF b9 is out. I've sort of migrated to Chrome anyway, it seems much faster, especially when I keep it running forever with 10 plus tabs open. FF loses responsiveness in that case, Chrome doesn't.
seriously though, I must be the only person on earth who's never had problems with firefox. I still think Chrome's UI is something of a travesty, but since it seems firefox 4 is determined to emulate it - and poorly at that - I guess I'll be sticking with 3.6 or migrating to Chrome eventually
@PC, sure skydrive sounds nice but when I tried it the interface was awful. haven't tried office web apps but I agree that google docs is meh.
