Looking for a replacement of a discontinued Youtube rating addon. This one works only if you have the video loaded already. That defeats the purpose. One should see the video approval rate before the video is loaded, to prevent clicking on spam videos. So the rating should show in the list after searching for a video and on your main page with recommended video's and whatnot.
Try "youtube ratings preview", "ratings preview for youtube", or "youtube video preview" in the add-on search.
