Firefox freezes on open in F43

Just finished installing Fedora and ran all of the updates as soon as the install finished. Firefox will not launch unless I run it with MOZ_ENABLE_WAYLAND=0.

It will freeze immediately and weirdly changing window focus away from it will refresh the UI and you can see page contents. However, the entire application still cannot be interacted with.

Running it from the terminal doesn’t show any interesting logs, just restorecon: SELinux: Could not get canonical path for /home/yak/.mozilla/firefox/*/gmp-widevinecdm/* restorecon: No such file or directory. which it shows when it works too.

I tried using the version from Mozilla themselves, the flathub version etc. all of these have the same issue.

I see that there is a Bugzilla specifically for Mozilla stuff. It can be found here. Maybe file a bug report…

In case you want to run Firefox, Thunderbird, TOR browser and alike with Wayland you can set once in the file “etc/environment” with the line “MOZ_ENABLE_WAYLAND=1”.

(I am not sure nothing changed these days).

I should have been more clear, my bad. This actually is what’s making it not work. If wayland is used, it won’t launch.

Yeah I caught that from your post.

I’m having this problem as well after updating to Fedora 43. It is working normally after the MOZ_ENABLE_WAYLAND=0 workaround. Thanks for sharing.
