Return YouTube Dislike is an open-source extension that returns the YouTube dislike count.
Available for Chrome and Firefox as a Web Extension.
Also available for other browsers as JS Userscript.
On November 10th, 2021, Google announced that the YouTube dislike count would be removed.
dislike field in the YouTube API will be removed on December 13th, 2021, removing any ability to judge the quality of content before watching.
This plugin will re-enable the visibility of the dislike count, fetching the total number of dislikes via our API, which in turn relies upon YouTube's Data API.
With the removal of dislike stats from the YouTube API, our backend will switch to using a combination of scraped dislike stats, estimates extrapolated from extension user data and estimates based on view\like ratios.
