On a system from today I tested firefox 66.0.5 again. Videos can't be
played at all as described above. I did download one to test locally, it
played perfectly well with decent sound, using mpv. It only crashed on
exit as follows:

So it appears for now only firefox video playing is affected.

Audio otherwise works - tested with beep media player (and, obviously,
with mpv).
