Ok,i have been using FF 2.0 since the weekend,to be honest im not that impressed. It seems slower,no Prefbar just yet and when first installed...the desktop icon had duplicated itself. Now everything working ok,just a little slow compared to the previous version 1.5
No Fasterfox either,although there is an untested version floating around the net.
Although Firetune seems to help a little bit.
Will tick resolved,and hope FF 2 gets a bit better.
