I noticed recently that the embedded youtube player (using the icon next to the picture insert icon,) doesn’t allow for full-screen mode in Firefox.

A quick search of their ‘help’ produced this thread:
https://support.mozilla.org/en-US/questions/1116018
Which says “This is about the HTML5 media player and this player requires a special allowfullscreen=“true” attribute in the outermost iframe for embedded videos.”
I tried adding the allowfullscreen=“true” attribute in the iframe, but nothing changed. I will now try the full embed code from Youtube and add it as html into this page:
Aha! The attribute in this embed says allowfullscreen, not allowfullscreen=“true”. I’ll try adding that to the source from the embedded player (this site’s icon.
Edit: After I tried inserting the allowfullscreen attribute, I now discover that the website has removed it !!! What gives, Bob ??
