Quick answer
A Firefox process may still be running after its window closes. Resolve the stuck session before attempting to recreate or delete a browser profile.
Understand the issue
Save work in any visible Firefox windows first. The profile contains personal browser data, so deleting folders at random can create a second problem. Note whether this happens after every shutdown or only after one crash.
Step-by-step checks
- Check for an existing Firefox window.
- Use the offered close option or carefully end the unresponsive Firefox process after considering unsaved work.
- Reopen Firefox and note whether the error returns.
