I saw something new in YouTube today. When I tried to watch a file (https://www.youtube.com/watch?v=mJVdiGpnH_s) the only resolution I could get was 360p. A video option labeled "Missing options?" brought up a YouTube help page (screenshot attached).

Why is Linux left out of this capability? It can't be because those formats are unsupportable in Linux; Chrome supports them for all of their browsers, including Linux. Why does Firefox discriminate against Linux users?

I somehow seem to have fixed it, all flags appear blue and all resolution options appear as they should. I'm not 100% sure how.

The last things I tried: I downgraded Firefox to the oldest version available (52.9xxx) and ffmpeg from 3.4.4xxx (ffmpeg-3) to 3.4.2xxx. Then re-upgraded them to current, rebooted, and it worked.

I still have no idea why that fixed it, but I know that since Google Chrome has worked properly all along with the same YouTube/Dash stuff and the different ffmpeg versions, the problem is ultimately caused by Mozilla/Firefox. They should fix it.

Thank you both for your help. I really appreciate it.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?


One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

Firefox on Linux fully supports the HTML5 Players such as used on Youtube whether in resolution or encoding being used.

You can check at https://www.youtube.com/html5/ as ideally all check marks should be blue.

If a couple are red then you may not have appropriate FFmpeg package installed as it may not be installed during Linux distro install. Gstreamer used to be used but not for at least a couple years now.

Sorry, but nothing is being blocked and there is no shield icon next to the padlock.

That was very good work. Well done.

It is likely that chrome comes with its own support for playing media files and doesn't have to rely on FFmpeg.

Thanks. That's possible, but it really doesn't let Mozilla off the hook. It should work seamlessly, not only like Chrome, but like it always did before.
