Hi guys i just reinstalled firefox and trying it over Chrome again. This tiny thing has been bugging me out a lot though lol.. When i make firefox go fullscreen on my second monitor i see a tiny bar on my main screen overlapping a little bit. On Chrome or Edge i don't have this problem. It's nothing major but it's annoying me more than it should i guess. I have added a picture but it isn't that clear to see. Within the blue circle you see a small white bar. That bar is 50% of my screen and showing on my primary monitor. Anyone know how to fix this?
