I have an older PC that I use for testing and I've noticed that when I use Firefox 3.0.5 that sometimes the PC crashes. Not just the browser, but the entire PC. I've yet to have a single crash in Opera 9.62 testing the same code.
I forget the exact specs of the PC, but I think it's an AMD Athlon running at 1600mhz and I know it has 1.5 gigs of RAM. Has anyone else had FF/jQuery crashing issues? I'm crashing ONLY when executing jQuery code! In particular animation/easing.
