That sounds like a missing driver or needs to uninstall the driver and reinstall the driver to connect. Firefox doesn't control what wireless cursor your using that is up to their own software update to fix connection issues. You should also check with the manufacture site support on the wireless cursor device as well for connections issues. I have wireless mouse/keyboard Logitech and updating my Browser doesn't affect them.

Well, thanks for wrecking my computer. The mouse doesn't work. All of the familiar tools have been re-named and placed somewhere else. I am off to buy a new one but I thought I would say thanks before I left because I am never using any of your programs again.
