Works perfectly, it's just sometimes slightly inaccurate with the number of dislikes.

Perfect!

Works great! My only criticism is that the way it works should be stated more openly. "Returns the ability to see dislikes" doesn't disclose that they're using a custom database for dislikes that extrapolates the number of dislikes a video "probably" has, based on the ratio of people who use the extension who like or dislike videos. This info can be found on their site's FAQ, but I don't think something so important about the core functionality of the extension should be so hidden, in a place only 0.1% of people will think to look. If it weren't for that small detail, I would rate this 5 stars. The extension has a lot of nice QoL features, like bar color customization, and different number formats.

Seems like they're adding bot dislikes in the results now.

annoying - it opens a popup after installation without the user clicking on anything and without the user requesting to view any page.

This extensions is good, but it is not updated right now. I hope it will be updated soon.
