I am running Firefox 3.6.3 on Windows Vista. I have discovered that over a span of twenty to forty minutes of running Firefox, it uses more and more of the processor, until it reaches 100% and eventually crashes. Once the program uses up the processor, there is nothing I can do to reverse the process except to close Firefox. Even if I close everything but a blank tab, the processor use continues; I have to close the program. Thankfully it only uses up one processor core (out of two on my laptop), but it's still very bothersome.This seems to be a common problem. Most of the fixes I've found involve telling Firefox to disable Javascript. This works, but I am designing a website that uses javascript, so I would really like to be able to repeatedly view my page on Firefox with javascript enabled, and without having to close and restart the program over and over.Does anyone have any suggestions?
