Help editing firefox 57 UI

edited January 2018 in Style Requests Firefox

I'm editing my Firefox UI and got stuck. How do I remove the light up when I hover over the back button? I want the color to stay the same regardless of me hovering over it or not.

So far I have

background-color: #0c0c0d !important;

Also how do I make these lines only 1 pixel? It's usually gray but I made it red to see.

  • #back-button > .toolbarbutton-icon {background-color: [your color] !important;}
    #urlbar {box-shadow: none !important;}
