Please don't put 1 star, give the dev time to fix the add-on! I came here hoping to find answers because it stopped working, and saw that the developer replied to earlier reviews saying "youtube just had an update that breaks the extension for a large portion of users (some UI changes) - working on a fix, all will be good soon." I decided to give 5 stars because I trust that when it will be fixed, it will work as well as before YT's update! (and in hopes that it will compensate a bit for all the recent 1 stars) Be patient folks!
