Photos black on Facebook with Safari
At the end of 2017 there were reports on here of pictures appearing black on Facebook when viewed in Safari on High Sierra. I have belatedly updated to 10.13.6, with Safari 12.1.1, and have run into the same problem. Normal viewing of Facebook pages is OK. The problem occurs when I click on an image to enlarge it. And not all pictures -- just some.
Did anyone ever find a fix for this strange behaviour? I have tried the usual ideas of clearing caches.
