Firefox opening and closing several blank, white windows at PC startup
At OS (Windows10) startup, Firefox launches several (3-5) blank, large windows then immediately close themselves. Then, when I launch Firefox intentionally, gives back an error screen saying it could not reproduce the previous session. I tried turning off (false) toolkit.winRegisterApplicationRestart and also is manually closing all tabs before shutting off. What else can I do?
