Destroyed my selected theme and dark theme preference in YT settings with restore IMPOSSIBLE!!! I even wanted to report this trash on Mozilla, but restarting the browser after uninstalling this TRASH made me forgive this shithead, leaving a chance to fix this JUNK...

Why would an add-on that works on only ONE website need blanket access to ALL websites and data, ALL browser tabs, and ALL browser activity/navigation?

Compare that to the popular Enhancer for Youtube add-on which only requires permission for data on Youtube...interesting.
