I've just installed it so i haven't checked out any new features...but it was instantly noticeable that it way faster than before, it's the fastest browser I've tried by a long way.
Ive used IE for 10 years and just switched over to Firefox 3.5 yesterday. Best choice I've made in a long time! You don't know what your missing until you try it!
Holy shit, this thing is fast!
Had a beta 3.x something version earlier and upgraded to this one, it feels like FF on speed compared to what I had. Everything goes faster and I beliving it might be the fastest browser out there now. Compared it with Opera and IE, they both was slow as snails compared to FF now.
Is that something that will increase the speed a lot? If the different is barely noticable it's more a botter than it is worth, but if it actually is a noticable different (in loading java's and such right?) I probally will botter doing it.
