64 bit browsers ?

Ok heres the deal.
I have a new AMD Phenom ][ Quadcore 3.0 Ghz, Radeon 4870 HD 1gig liquid cooled GPU, with an MSI DKA790GX motherboard.
For the first 3 months i owned this computer, i ran it with XP Pro 32 bit. with absolutely ZERO problems. I found a deal online for Vista 64bit home premium, including a free update to Windows 7 when it is released in October for $124, and I also expanded the RAM to 8 gigs.
Now, The XP Pro 32bit with 4 gigs of RAM (although it would only recognize 3.25 gigs) ran MUCH faster than my current setup of Vista 64bit with 8 gigs RAM .
My real problem is this, Firefox now gets hung up after i visit several web pages.
I have to go into task manager to kill the firefox process (which doesnt always work) and sometimes i have to restart the whole system before i can browse the web again, Not only is this very inconvenient, but also annoying as all heck .
I love Firefox, and hate to leave it, but if there is a browser designed to run specifically on Vista 64bit systems that some of you have tried and found to be reliable, i would much appreciate knowing about it . I am currently working TONS of hours, so I dont really have the time to do much research on this subject.If anyone has any advice on this subject, i would greatly appreciate it !
Thanks for reading this !

 

I am using Google Chrome with my vista 64. I use IE sometimes too, but I rally like Chrome so far. I like the bookmark tabs on the top of the screen.
Sorry I can't help with firefox. Have you tried reinstall? Good luck

 

Minefield sounds very interesting, ive already downloaded that and will give it a try. Ive already got Firefox 3.5.1, that's the one im having problems with . I actually dont like flash video, because they are largely used for advertisements, and I don't care for You Tube .
I only use adblock plus and the filterset G updater with the Firefox.

 

im trying minefield, and using the newest IE as well .
They all stop working after a fairly short period of time, and have to be restarted.
Seriously i think i may just reinstall XP Pro 32 bit and wait until windows 7 comes out. Im getting really sick of all these problems - i had absolutely ZERO problems with XP .

 

i cant get browsers to work. They will work for a few minutes, then freeze up, disappear from the task bar, and stay on the task manager processes list where they take anywhere from 3-5 minutes to end after i click "end process" . In the meantime, i am unable to browse the internet, and after the process has finally ended , i can no longer browse the internet until i restart the system. Vista is complete garbage, and i am now going to re-install XP and use that problem-free until windows 7 comes out, at which time i will see why THAT doesnt work properly . LOL
thanks for your attention .
I HATE Vista, i have had nothing but problems with on it the 2 machines i have, and will never try it again .
XP PRO, HERE I COME TO STAY !!

 

Wait a minute, i just downloaded OPERA and it seems to be working well without crashing, now if i can only find an adblocker for OPERA, id be happy !

 

nope. Opera is doing the same crap.
I am re-installing XP Pro as i type this on the other computer .
Vista sucks.
Period .

 

ok, so now ive got XP Pro 32 bit re-installed and everything is running smooth as glass.
I just dont understand why Vista blows so hard .
I wasted my money .
Anybody want to buy an unused (unused as in not being used currently) legit copy of Vista 64bit ? lol
