I recently upgraded Firefox and now I cannot use it if I want to watch something involving Adobe Flash because it crashes. I read your article and made sure I am up to date on all programs through Firefox check page. I reset the timeout on the adobe flash to -1 per your article. Your article states it may crash and just re-load it. I have done all your advice and it still will not run. I am now using Windows as my default browser because I don't have time right now to research this on my own and solve it. I don't know if you are aware that the fixes you suggested are not fixing the problem.
