Will not open as says already running. Systemrestart does not work.
When attempting to open Firefox the following message appears:
Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.
Restart does not solve the problem

To fix the problem, do the following - 1. First go to task manager and ensure that all instances of Firefox.exe are killed.
the rest of the recommendations were deleted by a moderator - I don't know if this posting was intended as "cute" or not, but advising a Firefox user to delete all their Firefox personal data files is wrong
