I closed the only opened Firefox process that was running. Then clicked the Fox to start Firefox again. I received a message: Firefox is already running, but not responding, to open a new window. You must close the existing Firefox process, or restart your system. This is a stupid message since there is no Firefox in process.

This happened

Not sure how often
