1. Retarting device , browser 2. updating device , browser 3.disabling hardware accleration on FF 4.checked for driver updates for my GPU 5.disabled any extensions or add-ons 6.run FF in tshoot mode 7.checked that windows media fetaure is installed

What security software are you running? If you're running win pro, try the below Sandbox option to see if you have the same issue. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/

You can check the Web Console for relevant-looking media messages.

I have this problem too. I'm using Fedora 38 and Firefox 115. I can't play any videos from any site. The message reads 'This content doesn't seem to be working. Please try again later.' I have uploaded an example from the bbc website.

Error 6102, 5000 and 5001 are shown when I right-click on the error message.

Install ffmpeg on Fedora with the RPM Fusion repo.
