About 2 minutes into every, ad I do mean EVERY session, Firefox crashes and won't respond to any commands. I have to unplug the computer to restart it. No it DOESN'T matter what website it's on...... it will crash just as easily on Ebay as it will on Wikipedia. If left alone.... about 20% of the time Firefox will resume operation after 4-10 minutes..... the other 80% of the time it will remain down infinitely. Yes I HAVE disabled Hardware acceleration.... to no avail, it crashes just like before. If a video is playing in the background, sometimes, SOMETIMES the sound will keep going, otherwise it just dies too. The machine is a Windows 7 ultimate with 4 GB of DDR3 RAM and a 250GB Western Digital Hard drive. I need to know what to do because I am getting REALLY tired of hard restarting my computer every two minutes. (It probably isn't very good for the computer either.)
