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.
Consider yourself lucky that you are not visually impaired and need high contrast and/or large themes.
Again, how would not providing any Linux app at all be preferable over an Electron app? How would it lead to you having a better Linux app?
