For the 2nd time this week I have had a web site for a webinar inform me that Firefox (on Ubuntu) does not support audio and video and that I should switch to Chrome. How can that be?

Make sure you have the latest FFmpeg and libavcodec packages installed.


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

Patent and copyright restrictions are among reasons why many Linux distros do not come with packages such as FFmpeg in a new install as it provides codecs needed to fully support HTML5 players being used for video, audio and even games now instead of using the Flash Plugin.

As you are using a flavour of Ubuntu so perhaps see https://linuxconfig.org/ubuntu-20-04-ffmpeg-installation or https://help.ubuntu.com/community/RestrictedFormats to help you get FFmpeg installed.
