This extension is really good, though it won't be necessary if YouTube themselves canceled the dislike policy but since they are refusing to that this is a good option

Giustizia è fatta, grazie.

Not working

A few times its inaccurate or glitchy.

que bueno que se puedan ver otra.

que bueno que vuelva!!!

Look what you have done YouTube. Look at what you have become. I am YouTube, I am Become Advertisement. Anyways, so thankful for this super useful add-on! Can't imagine using YouTube without it. Hope it keeps working for a long time!

Does not work for me at all. (firefox) If I go to a new youtube video with little or no likes/dislikes and click thumbs down I can clearly see it give a thumbs up instead. Has been doing this almost as soon as this came out. I think this is a scam probably by youtube to make people THINK they are giving thumbs down but actually giving thumbs up.
