I have a problem with the videos and I don't know why it doesn't work correctly in firefox.
In the HTML I have created the HTML5 video tag and I have inserted several video formats so that it can be seen correctly in the browsers
<video id="video" poster="img_video.png" width="88%" loop controls tabindex="5">
<source src="./video.mp4" type="video/mp4">
<source src="./video.wmv" type="video/wmv">
<source src="./video.ogg" type="video/ogg">
<source src="./video.webm" type="video/webm">
</video>
When testing it in browsers (Chrome, edge, explorer, Opera and firefox), it loads fine in all browsers and when I press play, the only one that fails me is in firefox that stays blank as if trying to start but does not play it.
Could someone help me to make it work correctly in this browser as well?
Thank you very much
Can you check that in the firefox options (by typing about:config in the address bar) the line media.windows-media-foundation.enabled is set to TRUE ?
Also try changing the order of the videos, putting the mp4 first and the webm second
Another option that you can try, add the tag codecs="vp8.0, vp9.0" to the webm
