Every time I start the computer or reboot and open firefox I discover that it isn't the default browser, as reported in the firefox settings menu. I then go to Defaults apps in control pannel settings and set Firefox as the default which sets the default to satisfy the setting menu which then reports that firefox is now the default browser. The next time I turn on the machine or reboot and check the settings menu I discover that firefox is not the default web browser. How do I set firefox as the default browser permanently so that I won't have to do this each time I start the computer? Thank You.
