Hi, see if it is running in the Task Manager - Ctrl+Shift+Esc > Applications tab, if it is, select it and click End Task.
Hope that will help.
The problem may the firefox.exe is running in background.

Create a new profile as a test to check if your current profile is causing the problems.
See Creating a profile:
- https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem
