This is still spyware. Use either an OLD version from the original author (2.0.7 works fine) or Stylem created for Pale Moon and Basilisk, and based off Stylish 2.07, works fine on Fx 52.9 ESR and probably on other versions as well. Stylus is NOT a good choice since a main reason for using this extension is so one can modify the UI and you cannot do that with Stylus but you can with Stylem.
