My firefox crashed and I re-installed it. Now it says one copy of firefox already running and the software does not open
My firefox crashed and I re-installed it. Now when after re-installing I tried to open the application, it gives me a message that a copy of firefox is already running and you cannot open another copy of the software.
I checked and removed all firefox documents and re-installed but the same problem occurs.
