I have tried uninstalling and reinstalling Firefox several times. Every time I try to open Firefox I get an error message saying "Close Firefox"," A copy of Firefox is already open. Only one copy of Firefox can be open at a time."

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
