Remove the X from the tabs when not selected

I LOVE y'alls new splitscreen feature, BUT I also noticed ya'll put the X on the tabs so that at any time even if unselected, you can close it; Is there any way to make that x appear only when selected because the main reason I used firefox in the past was because middle click was it's own dedicated way to close tabs making selected tabs literally careless and SIGNIFIGANTLY time efficient, but now that that x is on the tab at all times, it gets in the way and IT'S MAKING ME CLOSE ALL MY SPLIT TABS. Please, as a loyal firefox user, with either tell me how to remove the x's or please make it an official option to have them off. Thank you for your time.
