How would I highlight the currently selected tab? I was able to customize a previous userChrome.css project to change current-selected to a shade of orange with the following code.

.tabbrowser-tab[selected] .tab-content {
  /* background-color: #33cc33 !important; } */
  background-color: #ffa31a !important; }

Have fiddled with getting the same result in my installation of CustomCSSforFx, but this project is much more complex than the previous one.
