I can run Firefox once after starting the computer. If I close Firefox, I cannot run it again. Any attempt to start says there is an instance of Firefox running so it cannot start. I did some research and for that running the following yielded some indication of a problem that I cannot seem to solve.

>taskkill /F /IM firefox.exe ERROR: The process "firefox.exe" with PID 10220 could not be terminated. Reason: There is no running instance of the task.

Something appears to have left this PID so that the computer thinks it is running when it appears that it isn't there.

Please advise. [edited email from community support forum]
