I've found a bug. When a new youtube tab is opened, the icon of this extension has a ON on it, but the video will not be replayed as indicated. The next video will be played after this one finished. To fix this, I have to click the icon, and it's interesting that it will not flip to OFF, it still remains ON on the icon, and then the video will be replayed correctly then.
