It's now working in the new YouTube UI.

This no longer works since YouTube changed the layout.

works well, too bad youtube removed dislikes

knkhnhk

As it should be by default. Countering the woke no hurty-feely agenda by you tube which removed the ability of the people to express their dissatisfaction. Invaluable.

Broken with new beta watchpage

Anyone that has issues with the extension after the latest YouTube design change, please use
Enhancer for YouTube extension to bring it back to the old YouTube Layout, this will allow the extension to work properly again!

Does what is says on videos. I noticed for community stuff where it shows the likes under the previews it doesn't work there but that's minor.

dislikes yay :D

A must have for all Youtube users.

Didn't even have to restart the browser, all windows immediately show downvotes now.
