After Firefox has been opened once and then you try and open it again, a message appears stating - Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your computer. It is then NOT possible to close Firefox, so I restart the computer, but before it will allow that I have to force - End Program - NetscapeDispatchWnd - End Now.
