My Firefox started crashed yesterday and I haven't been able to open it since. When I try to open it, I get a pop up that says "Firefox Closed Unexpectedly during startup and then the Mozilla Crash Reporter turns up on the screen. I've tried to open in Safe Mode with no luck and I've tried to reboot my computer, I've made a fresh clean install of the software but same mistake shows up. I can't seem to access any crash reports in my application support either.
