There’s Now a Browser Extension That Lets You See Dislikes on YouTube Again (For Now) - Gizmodo

If you’ve decided that you absolutely cannot live without seeing the number of dislikes that videos get on YouTube, there’s now a way to get them back, at least for now.

The extension obtains the data from YouTube’s own API, which still shows dislikes when it’s used for public data, and restores the old layout we were used to seeing on videos before YouTube decided to axe dislikes last month to address harassment problems and “dislike attacks.” Return YouTube Dislike was spotted by 9to5Mac.

(Creators can still view the number of dislikes their content receives; the number is just not available to the public. Individual users can also still dislike content to help curate their recommendations).

The developers claim they “save all available data” to their database to ensure it will be available when YouTube shuts down the dislike counts in its API.
