Windows 11 Pro - Dell XPS8940 desktop - i9
Firefox will not play video from a website. If I save the video, it is a MP4 file.
Windows Media Player and VLC will play the video file.
But the browser shows the message:
"No video with supported format and MIME type found."
Chrome and Edge will play this video correctly in their browsers.
Firefox will not play the video on 3 different computers, and even when a different user account is involved (without Firefox sync).
The evidence seems to point at firefox.
The website is a Wordpress site.
Is it possible that the website is the problem?
If so, why do Edge and Chrome work?
I uninstalled Firefox (latest version) and reinstalled it.
Not fixed.
My windows updates are current, as are Dell updates.
This is stumping me. I hope someone can help.
