Foxfire Browser
Foxfire icon shows up again on my Mac's dock every time it is closed. You then see two (2) icons on the dock for Foxfire. This begun to happen after the MacOS Monterey was upgraded to 12.6.5. I have tried to delete Foxfire and reinstall but that did not solve the problem.

Try to enter 'about:config' in the address bar and switch dom.quotaManager.backgroundTask.enabled to false.
