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.
You assumption that I am clueless just shows you have no idea what you are talking about so I'll end up all arguments there. If you wish to prove me wrong, find me one Electron based application which supports high contrast themes and actually took care not to use colors that are problematic to color blindness.
