Here recently if I leave firefox open and don't use it for a while, when I come back to it, it is frozen and task manager says it is not responding. I have to close the process and restart in order for it to continue working. Its not using more then the normal amount of ram and I have dual Xeons, which are only being 25% utilized at most at the times. So I don't think its a resource issue, what else should i consider? I have ran adaware and AVG antivirus which both found nothing.
