For some reason, I haven't been able to get Firefox to play embedded Youtube videos here, specifically ones that I post. This has been going on for months. Since I can click on the "play in Youtube" and play them, I haven't spend much time on it until now. Today I went through a litany of "solutions" present on the web, and no joy.
Here's a typical video: https://ogrforum.com/...7#175990811270632367
Here's what I get when I try to play, it hands with the constantly rotation circle.
I've done all the usual things, cleared cookies, started in debug mode, etc. Nothing seems to cure this.
