This happened

Every time Firefox opened

Chosen solution

Well, here is my reply to my own post.

After reading some of the messages posted here about possible solutions, I tried deleting all YouTube cookies (tools > options > privacy > show cookies > youtube.com). Then tested on a site with embedded video that would not play previously and on YouTube site directly--both worked!

The poster with the cookies suggestion also suggested changes to "exceptions" but this was not necessary at least for me.
