autohide_toolbox.css Feature Request: resize window?

[u-Sir]

in latest version, firefox will leave a line on the bottom when I using taskbarhider to hide the task bar on windows 11. but there is no line in second screen:

a line on primary screen(click the pic to view):

is it possible to remove this line?

[MrOtherGuy]

Probably not. Style changes shouldn't affect the size of the window and it sounds you want to make the actual window a pixel taller. Style changes should only affect what is inside the window.

@MrOtherGuy this is highly unlikely but I wonder if it's possible to paint that line a different color? I suspect that it's drawn outside of the browser DOM but I don't know how to verify this suspicion
