Does it work if you start Firefox in Troubleshoot mode

Yes, it helps. It works when use "Troubleshoot mode".

Does it mean it is a problem with one of the plugins?

Comment 6

[Greg]

It still works even without the Troubleshoot mode with plugins turned on.

So. I could say it solved the problem.

That is very strange. Troubleshoot mode changes some settings and disables extensions, but they go back to normal once you go back to the standard mode.

Did you restart the browser at some point after you started seeing black rectangles instead of content?

Frankly speaking, I don't know.

I usually keep it open. So probably turning on the troubleshoot mode was the first restart in a week.
And it started like a week ago.
