There hasn't been a public API for pulling official numbers for years now. These apps just invent fake numbers based on extrapolations from the tiny minority of people that install the apps, which self-selects for a sad, dislike-obsessed population of people, skewing the numbers more negative than they actually are.

Dont work anymore.

Suddenly stopped working for no reason. Toggling the extension/reinstalling does nothing.

Doesn't work, constantly glitches and breaks YT. Often shows you removing a dislike when disliking a video. Just flat out doesn't work.

Не работает + саппорт юкрэйн meh

Crashes the browser.

Final update: I was pretty gullible in thinking that the downvotes would actually be real. What I've deducted that they're actually just a depiction of what the extension thinks it should be based on even your own vote. Bottom line is the downvotes aren't actually real this extension merely produces a count to fit a narrative based on your own vote. Silly of me to think that a third party app would change something like that on youtube's websites. I do feel pretty had tbh.

I actually think it does work. You have to do some password logging in (to check to see if youtube's just honoring your vote while logged in) and out due to youtube's way of displaying the downvotes, but with this app you can see them regardless if you're logged into yt or not which I later found. So when I logged out, closed browser (cookies deleted) and then opened browser to the same vid - and not logged in....I could see the downvote in-fact had changed. I did this with both downvoting and then clearing the downvote by upvoting and it does seem to register my change in the vote.

Stopped working

no representa la realidad, refleja la opinión de gente que es mas propensa a usar el dislike (incluyendome).

No longer works.

I liked it at first but now knowing it's more or less just a low sample size hallucination turned me off of it entirely. It only aggregates opinions of users that use the plugin.

This of course isn't the plugin's fault as you did your best but ultimately this shouldn't exist at all and should be taken with a tremendous grain of salt

completely inaccurate and doesn't match with the actual dislike count by magnitudes in many cases

Tried this extension several times. Never worked on Firefox.

Provides demonstrably incorrect info, and the developer seems to be a thin-skinned child.

Does not work whatsoever

Can be botted very easily. Which is why it shows very inaccurate data.

Provides wildly inaccurate data when compared with the real numbers. Entirely useless.

inaccurate and manipulated
