I've been using it for about a year (on chrome) and with my youtube vanced and it's very handy.

Honestly, we shouldn't have to install this to have dislikes back. YouTube shouldn't have removed them in the first place. In regards to the extension itself, it does a great job tallying up likes and dislikes for videos. I would definitely recommend this to anyone using YouTube.

I choose what I don't like!

EDIT - if it stops working. Remove it completely. Close Firefox. Re-add it. It then works.

This is a crtitical extension for anyone extensively using YouTube. Nothing too fancy on the surface, it allows dislikes to be displayed again.

Under the hood there's quite a bit going on, and unfortunately it doesn't always work smoothly, sometimes dislikes are still not visisble and accuracy isn't garaunteed. Still, the developer's efforts are greatly appreciated and when it does work it adds back a lot of the value YouTube has been trying to take away from its platform.

Must have extension for absolutely any user.

absolutely indispensable, removing dislikes is the most backwards-thinking "feature" youtube has ever implemented, the fact that we have to install an extension just for this to work is ridiculous, i hope google takes the memo, y'all are doing god's work, fantastic extension.
