I’m asking this because I have this ‘problems’ but don’t know how to debug to try to make the report.

  • Some webpages don’t work Problem with Firefox 92.0 (64-bit) and unsplash
  • Some video teleconferencing services:
    • Crash when I or anyone share the screen or after someone shares screen.
    • If no crash when other people share screen the video is too slow, like 1 frame per 10 minutes.
    • At beginning I’ve think that this could be a driver problem so i asked this Why AMD driver crash? but no get a answer.

Almost all of this problems are solve if I use the version from firefox webpage, does the repo version of firefox is in some strange way optimized for gnome and wayland rather than kde with x11?

That’s probably only something the Fedora Firefox maintainers can answer in detail, unfortunately.

The spec file for the Fedora build is here, so you can see what modifications/patches are used in our builds:

https://src.fedoraproject.org/rpms/firefox/blob/rawhide/f/firefox.spec

(I don’t know where to look for the upstream Firefox build information)

(If you’re having issues with the package in Fedora, it’s best to file a bug if you haven’t already so the maintainers can investigate. We can discuss bits here on the forum, but the maintainers don’t necessarily monitor forums.)
