:ame, could you get an url to a crash report from about:crashes ?

When running firefox-trunk without setting the GDK_BACKEND environment variable, firefox starts normally albeit in XWayland mode rather than in Wayland mode.

This url doesn't work, I get 'Hmm. That address doesn’t look right.'
Maybe the Ubuntu Mozilla team changed the functionality to support their own bug-submitting system. I'll try to generate a crash report in another way.

I think it will be easier to just download Firefox nightly directly from Mozilla. I'll do that and then report here.

The bug doesn't reproduce on the version downloaded directly from Mozilla, so this is probably a packaging issue. I'll close this bug now, thanks!
