I use Safari and Firefox(not the new 2) and I tend to have quite a few tabs in quite a few windows opened at once. Generally around a dozen or two tabs each in half a dozen windows, but sometimes a lot more. Not with images or videos, nothing taking up a bunch of space, just lots of pages. And no other apps running. The problem is, after a while the browsers will freeze sometimes, or worse, OSX will freeze. When OSX freezes, it's especially weird, because on the right hand corner freezes, with the volume, wifi, user switching, time, and spotlight, and on the left only the apple symbol becomes frozen. Meaning the beach ball forever is there. When I relaunch finder, it's exactly the same, time frozen at the exact same time. This happens on two computers. The very last version of the G5 17" iMac, and the very last version of 17" G5 powerbook. Both have 1.5GB ram, both have at least 15GB free on hard-drive. All the latest updates I know of. Any ideas of how to avoid this? Clean up utilities, better browser or plugins, more ram, just need a faster computer, or unavoidable in general? I don't know if there's a "no duh" component I'm missing here, but I'd appreciate any help.
