Are you sure the title bar is an SSD title bar? I think it is a CSD one.

waiting on reply to #1

Comment 3 Plata 2024-04-27 11:37:33 UTC

Can also be that it's CSD. Is there a way to verify this?

Firefox uses CSD by default, and there isn't anything we can do about it with GTK, because it doesn't support xdg-decoration, where we can enforce decorations to be (not) drawn by the compositor without the app showing its own.
With Firefox specifically, you can configure it to use server side decorations by making it use a title bar, in which case it should be hidden automatically.
