Unable to access Facebook from Firefox
On my iMac (iOS Big Sur 11.6), two days ago suddenly every time I tried to access FaceBook, I just got a black screen. No delay in going to black, no error message, nothing but immediate black. I can access FB with Safari and Chrome, just not FireFox (which is my default browser). It's been problem-free up until now. Any thoughts on what the problem might be?
