Preloaded firefox bundle missing codecs

you can install a browser from flathub with flatpak. you can check a browsers codec support at https://html5test.com/
you can install ffmpeg with bash script from here. you can also try to install ffmpeg from source, see here
the vlc bundle is also missing codecs, and you can also install that with flatpak

This is expected and documented. See: FAQ — Documentation for Clear Linux* project

Greetings,

I too wished for Firefox to support more codecs when trying Clear Linux for the first time. So much so that I too automated the installation of FFmpeg and dependencies to include vp9 support. Afterwards, Firefox scores 512 out of 555 points https://html5test.com/s/2fdc395767a6bb55.html.

Added wish request to swupd, issue 1587, for repair to not break NVIDIA driver installation.
