There is a bug in the currently available version where the dislike number shows up on the share button, instead of the dislike button.

It's been fixed already, but the new version just needs to be approved in the various add-on stores. If you don't want to wait, just install the userscript version from the official Return YouTube Dislike website, but if you do that, make sure you disable the extension.

most of the time it works in the sense that it displays the dislike counter, but it often breaks the ui a bit. for example, currently the dislike counter is displayed on top of the share button. otherwise no complaints.

Works great, until it doesn't, like right now. It broke again a few days ago. I tried to update t 3.0.0.12, restarted my browser and everything, still doesn't work, so I guess I'll check back in a week. Still giving it 5 stars because it works well when it does which is most of the time. Last time it broke, he came out with a fix pretty quickly.

The Dislike counter doesn't seem to be working anymore. This add on is due for an update

Doesn't work anymore

ENG: Unfortunately it really doesn't work anymore. One can only hope for an update, but so far this is the only addon that has brought back the dislike button.

DE: Funktioniert leider wirklich nicht mehr. Man kann nur auf ein Update hoffen, bisher ist dies aber das einzige Addon, das den Dislike-Button zurückgebracht hat.

This extension used to work. Unfortunately, as I am browsing on Firefox 120, the dislikes show in the share button for some reason. I think this is due to YT changing their API and not the fault of the developers.

no longer works!

It lags/bugs out my youtube player. thanks to a random redditor i managed to figure out what was causing the problem and removed the extension.

It doesn't count my dislikes, so its functionality is questionable.

It works again now

It's really good. As of the latest update, I can only see the #of likes and shares now. The ratio bar is visible, at least.
