Flash recently started instantly crashing in firefox but works fine in chrome

I currently use the most up to date versions of firefox and flash player and was having no issue last night but today trying to view any flash content will result in an instant crash. No loading just grey box with a sad face saying flash has crashed. I have turned off hardware acceleration in flash and in firefox as well as unticked the protective mode box and still nothing I can not look at or change any other settings now as it just will not load it just straight crashes. I just tried to view flash content in chrome and it works without issue but on firefox instant crash. Is anybody able to help me with this? I have no even turned my pc off since the time it was working and now so I have no idea what is going on with flash.

Edit: Just tested with the edge browser and flash is working fine with it as well.
