Lately I've become interested in using Plasma with the Global Menu widget. Of course that includes Firefox, and after some research I've found that it works "out of the box" in KDE neon and in Arch-based distros when using firefox-kde-opensuse from the AUR. Naturally I tried in Tumbleweed but I could not get Global Menu integration for Firefox working (even when installing libdbusmenu-* and appmenu-gtk). My conclusion is that firefox-kde-opensuse is not Tumbleweed's Firefox, contrary to what the name would indicate. Is there a way to get Firefox to integrate into the Global Menu widget in Tumbleweed, ideally using only default (e.g. secure) repositories?
