Ive been using the beta/RC's and I do have2 say: Slick! Ive been a firefox user for a couple years now and its just getting better imo. Im tempted to say, even though evolutionary, this is the best browser ive used to date.
My firefox 3.5.7 was crashing all the time. SOOO Annoying when talking to ppl on FB. My rig which runs crysis maxed out could not keep up with my typing in facebook.
Why are they making it faster? If you want faster buy a new PC, that's what keeps the economy growing.
What they should be doing is working out how to monetize this product. Figure out how to lock in current users and then figure out how to squeeze them as hard as possible.
