When I first open firefox, a window opens in the center of the screen. The title of the window is firefox.exe-Application Error there is a red circle with a white x on the left side of the box. Written in the box is: The instruction at 0x10008d37 referenced memory at 0xfffffff. The memory could not be read. then it gives two choices. Click on ok to terminate the program or Click on cancel to debug the program. Cancel and ok shuts down firefox. If you move the box out of the way, you can use firefox to surf the net.
