A copy of Firefox is already open. Only one copy of Firefox can be open at a time -- HOW DO I SOLVE THIS?

Posted

I have read the other threads and tried what they suggested and am still unable to solve this.

I am using OSX 10.7.5

I have tried uninstalling and reinstalling firefox. This did not work.

Any suggestions?

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

See "Creating a profile":

If the new profile works then you can transfer some files from your old profile (if there is one) to that new profile, but be careful not to copy corrupted files.
