It worked up till about a month ago. Now, the dislike button is broken. You can't see if you've disliked a video or not, and there's no number or thumbs down count.

Currently not working. Needs fixed thank you!

Completely broken. No dislike icon, so you can't tell if you disliked a video already, and the count is in prose ("one thousand and twenty..." instead of "1023"), which is so long it won't fit in the button and gets cropped, so you can't read the count either

marche pas

It hasn't been updated in almost two years and is very broken.

The add-on doesn't display any real data. Useless.

it works but is outdated and has bugs because of that.

Kind of strange that while the dislike count is displayed, the thumbs down icon is absent. Additionally, for some inexplicable reason, the Firefox extension hasn’t been updated for a considerable time. Although installing the user script instead resolves this issue, I really hope that the Firefox extension is also updated soon.
