Crashing Firefox and Safari on netbook?

[JoQ]

Hi!

I have an Asus 1005HA netbook with an Atom processor and GMA950 graphics. I've installed Snow Leopard and it works great! No problems, except that Firefox crashes very often!
When I open links that are a little bit heavy (not like google ) it tends to quit immediately. This is very annoying, and same thing happens with Safari, not very often though. But when playing flash-video like Youtube and others this happens alot more in both browsers! Another thing i notices, flash video is laggy when the power-plug is unplugged, do the processor throttle down? I have no such kexts!

Please help me solve this!
