Bill, the page linked is a tutorial to show you how to code videos in html5. What you pasted is the required code. If you click on the "Try it now" button, you would see the code in action, and a video would play. Firefox 78 is not that old, and will certainly work with html5. Every version since version 5 does. It's not the age of your browser or system, it's your lack of understanding. Website coding is a constantly moving target, and you have to be able to adapt to new techniques, or else be left behind. As others have said, flash is a dead horse. You really need to stop beating it and learn modern ways of doing things. Read the W3schools website and you can learn html5 and provide a usable website to those who want to use it.

You are looking at example code. It is not a comment on your browser.

Also, as per post #3 to play audio in a browser you use the audio tag, rather than the video tag. The syntax is the same:

Firefox 78 ESR was first released on 30th June 2020, and Firefox 78.3.0esr was released on 22nd September 2020.

Apparently there was a 78.4 esr released last Tuesday, but their browser is still fresher than some of the food in my cupboard.
