i should have been more specific: client-side decorations.
boils down to not having a separate titlebar. by right clicking an empty spot in the tab bar and clicking “customize toolbar”, there will be an option to disable it, and get more vertical pixels of screen space. it will work more like windows and most linux environments. i don’t know why OP’s isn’t doing this by default, it should.
if you want even more vertical space, go to about:config, set compactmode to true, then a more compact ui will be available in the customize toolbar menu. vertical tabs are not bad either after you get used to them.
CSD?
