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.

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.

It's an arms race with youtube at this point. works really well whenever yt doesn't choose to f sh*t up.

It has worked all the time but I just created a new YT account and it doesn't work on that one for some reason.

YouTube keeps trying to break this, but the author seems to be doing a good job keeping it updated:

this version works for me

Looks like the addon does not work in Firefox 118.0.2 under Linux :-(

great for helping to inform me, but can sometimes slip with youtube updates

It was nice while it worked, but it seems to no longer be working. I can't see the dislike counter anymore. Maybe I'm just impatient because apparently, the creators of this add-on post changes to GitHub before Mozilla approves them for release here.

works great although sometimes it doesn't show up

Sorry Dmitry this add on is only partially working on latest Firefox 64 bit version for Youtube. It works on the short videos.
In the comments and replies it is not working at all. Also on the main video title Like/Dislike it still only shows the likes. Interestingly now it also shows "Disabled by Owner" which I never saw before the add-on. Hopefully you can resolve it.

Update: The Dislikes are now visible on the Main YT videos - Thanks.

Is there any way to see the Dislikes in the Comments section of the Video ?

Sometimes a little glitchy with the new updated ui, but works pretty well.

A few times its inaccurate or glitchy.

Occasionally it stops working but that's YouTube's fault. I had a very old channel with only a few videos, most of which having only like 20 views, and it got the dislike count perfectly! I had to sign in to that old account just to make sure! The only thing holding it back from 5 stars is the fact that it can remain broken for a few days before an update fixes it. Also it doesn't work on the mobile interface or TV interface, but those are only slight things.
