Firefox unable to play online videos

[Frank McCormick]

I am running Fedora 32 up to date. It is a relatively
new install and I noticed  a few days ago Firefox is unable
to play any online videos, including those on CNN.COM and Foxnews.com as 
well as other sites.
I get various errors including error #4 from CNN. On foxnews
the circular loading image just continues forever.

I noticed Saturday I believe Firefox was updated to 80.0.1.2 but I don't 
recall whether it was able to handle online video
before the update.

How can I debug this?

Thanks
