Since I discovered the existence of global menu on Plasma, I’ve been searching for a version of Firefox that supports it. While I’ve found patches for it, I don’t know if it still works and have the patience to compile it.
Kudos if it’s in the AUR pre-compiled.
If you don’t know what global menu is it just moves the toolbar to any panel you want like in the attachment.
EDIT: Compiled firefox-globalmenu from the AUR, turns out it doesn’t work with wayland :(
I find it very convenient. It’s always in the same place for every app that supports it. I’ve been testing Ladybird and it supports the global menu on Plasma. Something to keep an eye on.
