Build fails:
See https://gitlab.com/gbraad/flatpak-firefox/builds/3453471
I believe this happens due to a wrong icon:
error: Icon not matching app id in /builds/gbraad/flatpak-firefox/app/export/share/applications/org.mozilla.firefox.desktop: firefox
We probably should try adding
"rename-icon": "firefox"
If it doesn't work I think there's a switch to skip icons
