This does exactly what it's supposed to do, and a little more. It returns the dislike count.

Hello Return YouTube Dislike Team.
I found this addon very good at the beginning. And above all the 3.0.0.1. Update as the colors look pretty nice! But since YouTube introduced the new UI, you can't see the ratio anymore. In addition, you could see the ratio of bad tutorials with deactivated ratings in order to avoid such scammers. Now it just says disabled by owner. Unfortunately, some of the most watched videos have not been updated for 3 months.
Also, it often just says tomporarry unavaiable. And I don't think Return YouTube Dislike is bad because otherwise you'd never see the dislikes again, especially in YouTube Vanced, but the addon is just poorly implemented and the KellyC Show YouTube Dislikes v1.1.3.8 addon does a much better job.

works good but its broken when you go to shorts

Must have.

It may not be SUPER accurate but gives a good "mini preview" to what you might expect from the video.

I don't see the number of dislikes below videos. It worked for some time, but not anymore :(

Gooooooooooooood

Have been using this add-on for a half of year or even more and it is still one of my favourite add-ons out there.
Update: Thanks for update. Glad that mozilla finally approved it. Didn't think that I would miss ability to see dislike count this much.

Finnaly i can see the tremendous amount of dislikes on Disney videos again
