YouTube™ Ratings Preview is a free Firefox extension that shows the likes and dislikes bar over every video thumbnail in YouTube so that you can know its rating before watching it.

This extension shows a bar of likes and dislikes under every video snapshot. In this way, you can view the rating of the videos before watching the actual videos, so that you can avoid garbage and spot amazing ones.

In addition, you can move your mouse to the bottom bar and a tooltip will show up to tell you the likes percentage and the total ratings count. And you can also configure it to automatically highlight with a blue box the best videos in every page.

This extension uses YouTube’s batch data API with direct Javascript requests, resulting in a lightning fast loading of the bars (all of them at a time), and absolute minimum size and resource consumption.
