G'Day!

I've been having issues with media playback on firefox.

Almost any video source that isn't from youtube cannot play in firefox, giving the error: "No Video with supported format and MIME type found"

Testing the same video on Chromium has no problems.

Using Fedora Linux on an AMD system. And Fedora Flatpak build.

System specs below if required.

Any idea to get this up and running would be really appreciated. I think I already installed the propriety media codecs for fedora since the problem isn't showing up on chromium it looks like a firefox issue.

For a few months now I've been having issues uploading firmware files to my QNAP server's website. I was trying to update the firmware, but it wouldn't allow the file to even be uploaded. Would just get a general "error" with no help.

This past week a started having issues with 7digital.com not allowing me to download zipped music files. It kept giving an error about the oauth token not being passed through. (Error: Authorization failed for method <GET> and URL <http://media.geo.7digital.com/media/user/download/release>. Missing oauth_consumer_key)

Finally figured out that this is only happening in Firefox, Brave browser and other Chrome based browsers don't have the issue.

I've tried turning off the tracking and download protection in settings, but it didn't help. So, what's causing it?

Using Firefox 128.0.3 (64-bit) on Linux (NixOS).
