if they don’t offer the fix tomorrow or maybe next day- I’ll definitely try that process again only this time w/ safemode after reinstall and reset to true
I’ve been reading a few blogs on the issue , and they state mozzilla will be issuing fixes as soon as possible- so I’ll give it a few days- I hate running with the signatures enabled- but nothing else to do for now I guess-
Firefox 66.04 has been released to fix the problem.
