Excellent add-on!

Thank you so much for giving us back something that youtube never should have gotten rid of in the first place!

Based.

Расширение хоть и рабочее, только вот подсчитывает оно дизлайки поставленные именно с расширением

Doesn't wok anymore.

Sorry Dmitry this add on is only partially working on latest Firefox 64 bit version for Youtube. It works on the short videos.
In the comments and replies it is not working at all. Also on the main video title Like/Dislike it still only shows the likes. Interestingly now it also shows "Disabled by Owner" which I never saw before the add-on. Hopefully you can resolve it.

Update: The Dislikes are now visible on the Main YT videos - Thanks.

Is there any way to see the Dislikes in the Comments section of the Video ?

EN-US: Something that should have been there without the need for any extension/addon, but YouTube made this misguided and anti-consumer move to remove something that is basic in today's world. Let's face it, they only removed it because of the extremely negative reviews on YouTube's official retrospective videos. Anyway, in light of this, an essential and highly welcomed extension to enhance the usability and convenience of YouTube itself and how people are reacting to other videos on this platform.

PT-BR: Algo que já deveria ter sem qualquer uso de extensão, mas que o Youtube deu esse movimento errado e tão anti-consumidor de tirar algo que é básico nos dias de hoje, que convenhamos só tiraram por causa das avaliações extremamente negativas nos vídeos oficiais do Youtube, mas enfim, diante disso, uma extensão essencial e extremamente bem-vinda para melhorar a utilização e praticidade do próprio Youtube e como as pessoas estão reagindo aos demais vídeos dessa plataforma.
