Firefox has started freezing my computer for no reason. At first I thought it was MS trying to get me to reboot so they could install updates, but when I did a hard shutdown and restart, it wasn't. I couldn't use the mouse or keypad. Nothing on the keyboard worked. I have my keyboard plugged into a multi-usb adapter, so I tried unplugging it and plugging it into another usb slot, but that didn't work either. This is an intermittent problem. FF will work fine for weeks or months, then suddenly, it does this. I've switched to a new profile already, so that's not it. Is this a new bug? Please don't answer me by suggesting I do things I've already done. TYVM
