Windows 10: Firefox Will Not Open

I am the administrator, yet this happens. I also tried restarting and reinstalling, but those did not work. Please help!

FireFox

That's why I suggested this for starters, for the issue you report:

Firefox - Profile in Use

Scroll down on that page to the "Solutions" section.
The easiest way is to open the Windows Task Manager and to kill the Firefox process from there.
If that does not work, then proceed to the next steps in that tutorial: remove the "profile lock" file, etc.

Please let us know how that goes.

Thanks,
MM
