Update: Stopped working a day after...I don't know what's going on, but it's like youtube knows that I'm using it or something. So now after I downvote it will change, but as soon as I refresh the page it reverts back to where the number was before.... oh well it was interesting.

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

Seems to have 0 protection against bots or manipulation. If it has it is extremely poor. Might be useful for scam detection but seem to be very easy to manipulate. Perhaps add a warning for that to be transparent?

This Extension is 90% inaccurate, do not take the dislikes as true

it also can be manipulated easily.

It colors ratio, but dont shows dislikes

Absolutely nothing changes. I still can't see the dislikes on videos on Firefox.

WTF? are u talking about the thumbs down is still on YT! LOL it never left from what I know am in Germany and I see it every day since 2007
