my pc says Firefox is running after I close the browser, and will not let me access the internet. This continues even after I shut down and restart my pc. It even continues to do it after I uninstal, then reinstal Firefox. What can I do?

We tried uninstalling , tyen reinstalling Firefox, but we still get the error message that Firefox is running, and the PC won't open the browser.

We went to the Task Manager on our PC, which said Firefox was running, and told TM to close it. But, when we try to then open Firefox, we get the same error message.

See:

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.
