При включении дополнения появляется надпись Disabled by Owner, при этом не отображается количество лайков, а только дизлайков (на месте кнопки с лайками)! Разработчик читает? Проверьте еще раз сами и исправьте! При этом в Microsoft Edge дополнение работает на отлично!

Do not believe the reviews. This add on no longer works on the updated youtube UI.
