The addon works fine.... except that every media key is getting redirected to MediaPause when playing on YouTube. Would have given it a 5 star if it was able to properly skip a track instead of pausing it, if prompted.
Thanks for porting it to quantum! The only thing is that the keys just pause and resume the video, while in old version for ESR if i remember you could use the right buttons to change playlist song to next and etc. Anyways very good addon, i needed this so badly!
