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.
No no I only have the flatpak version of firefox installed yet in my taskbar it doesn’t use the pinned icon and on wayland it doesn’t have an icon at all.
What distro and desktop environment are you using?
