Firefox will not open or opens but will not show a window and must be forced to quit. 27 "iMac Pro running Big Sur. I have restarted the mac multiple times. I have uninstalled Firefox and reinstalled it, all with the same result. I have checked for updates and the computer shows everything is up to date.

Disregard above. It was opening on my wacom pen tablet which I had turned off. I'm an idiot.
