Its even worse when you force Firefox to use wayland its icon doesn’t even show.
Edit: Oh since everyone now is confused; I only have the flatpak version of Firefox installed yet it doesn’t use the pinned icon and doesn’t even use the firefox icon under wayland at all.
Sounds more and more like flatpak is a distribution atop of a distribution.
Good you can share libs, although I can’t see sense in sharing more than the absolute basic libs, and even then some applications will need different versions of the basic libs.
