Haven't seen flash crash in quite some time. Have you already tried running the flash uninstaller and reinstalling it?
Also, i'd try updating video drivers and then possibly disabling hardware acceleration.
Otherwise you may have to create a new profile.
Another thing you could try is to use a flash blocking addon so flash doesn't automatically load. That has served me well.
You can set Firefox to do that in browser now. In about:config, toggle plugins.click_to_play to true
Thanks lxskllr, I will give that a try. I may have made this sound like a HUGE issue for me, when in reality it is not. Just annoying at the most. I usually see this occur when I have had in instance of flash open for an extended period of time, which I normally do not do.
