I have cleared browser, refreshed Firefox and disabled Add-Ons.

Unfortunately, I am still receiving the "The Media could not be played" message for all videos on Twitter.

Everything works correctly in Chrome.

I even attempted to download the "Media Feature Pack" for Windows 10 (1903). Unfortunately, it is not available when I click Add Feature.

I believe this all started after I updated Windows 10 to 1903.

Did you check the Web Console for possible error messages and warnings?

If you block (third-party) cookies very strict then you can get cross domain issues.


Just to be sure:

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
