The API

This extension uses the Return YouTube Dislike API for likes/dislikes data.

If you would also like to see the likes/dislikes rating bar that used to be available on each video page, you can also install their extension.

Mobile Support

This extension also works on mobile browsers that support Chrome extensions, such as Kiwi Browser for Android.

Rate Limiting and the Cache Duration Setting

The Return YouTube Dislike API is rate limited by IP address, so if you notice that some thumbnails aren't receiving rating bars, you may be getting temporarily rate limited. If this happens, you will usually only be rate limited for about ~15 seconds before you can start retrieving new rating data, but you may need to refresh the page if you want to retry loading the rating bars for the thumbnails that got rate limited.

To help prevent rate limiting, this extension uses a cache, meaning that whenever it fetches data from the API, it will save that data and reuse it if needed for however long the cache duration is (the default setting is 10 minutes, but this is adjustable). This helps reduce the number or API requests that are made.

Also, the same global cache is shared across all of your browser's tabs and windows.

Exponential Scaling Option Explained

In the extension's settings, you can enable an option to exponentially scale the rating bar. This makes it easier to distinguish between highly rated videos (since most videos have a rating over 90%). You can see the difference between the default linear scaling and the exponential scaling here:

With exponential scaling, each reduction in 10% of the rating from 100% will half the width of the likes bar:

Rating Width
100% 100%
90% 50%
80% 25%
70% 12.5%
... etc.

Note: If you also have the Return YouTube Dislike extension installed, which adds a rating bar to the video page, this option will affect the scaling of that rating bar as well.

Special thanks to Qarthak for requesting this feature.

Why Use This Extension

Using YouTube usually involves browsing through many video previews. These video previews usually contain the following:

  • Thumbnail image
  • Video title
  • Creator’s name
  • Creator’s subscriber count (sometimes)
  • View count
  • Short description (sometimes)
  • Video length

We use this information to try to estimate the value of the content before exploring it further. A useful indicator of the value of the content is how valuable other viewers found it. The view count has some correlation with the value of the content, but on its own is unreliable. By being able to also see the video’s rating, users can much more accurately estimate the value of the content, resulting in finding higher quality content, saving time, and avoiding being clickbaited.
