Thông tin chi tiết
Hi Dan, as a Windows user, I am not aware of any secret Mac magic for this problem.
Assuming this began with Firefox 66, I wonder whether you might try installing Firefox 65.0.2 and see whether it can run. It may well want to update right away, but at least we can get a little bit of information this way.
