i've got a 1.25GHz powerpc g4 w/1gb of ram running os 10.4.11. my browsers, firefox and safari crash constantly. tried EVERYTHING. i finally entertained the idea that maybe i was crashing because my 80 gig hard drive was 10 gigs shy of being full. so i backed up all my important stuff and totally erased my hard drive to start from scratch. this worked great for about an hour, and now i'm back to the browsers crashing all the time again. if i watch video, like on youtube, i'll crash every time within 30 seconds i don't get it. i should mention that both browsers are up to date, as is my flash player. how can this still be happening even after wiping the slate clean? i haven't even put all my saved data back on the hard drive either.
