@Lucia Its not to make it look like something else, the screens are become wider and not taller, and it make more sense to move the the tab bar to side (vertical tab bar).

I hide the CLOSE, MINIMIZE & MAXIMIZE button as i am using Sway (a tiling window manager).

And to move, we can just press the mod button (CMD on macs and window logo button on keyboards) then just press the left mouse click on firefox to move screen.
