Hello! I am using the userChrome.css file to hide the nav bar (# nav-bar) and show it when hovering the tabs.

The following code works a bit, but when I open the developer tools they overlap. 

# nav-bar {
   z-index: -1;
}

# navigator-toolbox: hover # nav-bar {
   z-index: 1;
   background-color: rgba (0,0,0,0.8)! important;
}

#browser {
   margin-top: -45px;
}

Any advice to achieve the expected functionality? Thank you

#nav-bar {
  /* customize this value. */
  --navbar-margin: -44px;

  margin-top: var(--navbar-margin);
  margin-bottom: 0;
  z-index: -100;
  transition: all 0.3s ease !important;
  opacity: 0;
  background-color: rgba(0,0,0,0.8) !important;

#navigator-toolbox:focus-within > #nav-bar,
#navigator-toolbox:hover > #nav-bar
{
  margin-top: 0;
  margin-bottom: var(--navbar-margin);
  z-index: 100;

Hi, you can use &ltpre> before and </pre> after your CSS to avoid the forum mistaking it for wikitext.

Probably you need to inject some padding at the top of the dev tools and just waste that space. A good site for advanced CSS tweaking is https://www.reddit.com/r/FirefoxCSS/
