Hello there, I have changed my default browser from Chrome to Firefox because of the "v3 chains". I can´t get rid of the 4-5 px Border around my windows Browser frame. It reflects somehow parts of the onscreen-content... in the images you can see the YT-video that I was watching. It is pretty anoying... I tried some changes but nothing seems to work. I use the dark-theme in Windows-designs and dark theme in FF-Themes.. Yeah, it is one of these very little things that makes me wanna cut my screen with a chainsaw on the edges. Does anyone have a fix 4 that, plz? stay borderless.
