After upgrading to FF 11, the browser crashes regularly. It usually happens on pages with some sort of flash on it, whether it be a video page or even a page with flash ads. I have tried turning off the hardware option in flash. I tried turning any video downloading plugins off. I have also tried running in safe mode. Safe mode works best, but it will eventually crash after some time. I am able to surf in Safari with no problems, which leads me to believe the problem is not with flash, but with FF 11 and flash. FF 11 crashes so hard, I am unable to get a Crash ID as my whole machine freezes and I have to do a hard restart.
