I have no plug ins or add ons in my Firefox. I cannot play HTML5 videos at all. "Your browser does not recognize any of the video formats available."

What do you get on https://www.youtube.com/html5/ as all check marks should ideally be blue.

if at least a couple are red then you may not have installed FFmpeg as it is not normally installed during a Linux distro install. Ubuntu for example has a Ubuntu Restricted Extras for this.

I see six check boxes. The middle two are not checked ( H.264 and MSE H.264).

No worries, "wmf" is for Windows users.

You need an FFmpeg component for Linux for Firefox to decode H.264 video, as James mentioned. I honestly don't know the best way to install that, but your package manager might be a starting point.

So you may likely not have FFmpeg installed as it provides the codecs needed.

Okay, I found some pages talking about downloading the FFmpeg you all mentioned, but that looks like a lot of complicated coding to me. something beyond my skill.

Look in your package manager. As you appear to be using Ubuntu or one or the flavours of it it may be in the Ubuntu Restricted Extras as I mentioned.
