Thank you so much! I've been searching for a way to hide the top bar for a while now.

A better modification is this:

    #TabsToolbar > * {
      visibility: collapse;
    }
    
    #TabsToolbar {
      margin-bottom: -21px !important;
    }
You can also re-enable the title bar under hamburger menu > Customize > "Title Bar" at the bottom left.
