Enabling compact toolbar density

  1. In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

  3. Double-click the preference to display an editing field, change the value as desired, then press Enter or click the blue check mark button to save the change. These are the available values: 0 => Normal density (default) 1 => Compact density (my preffered setting) 2 => Touch density
