The YouTube dislikes from this aren't real. It's speculation based on people who have installed this extension, and not actual YouTube dislikes.

WHY @Ender_Noch VIDEO HAS -169K LIKES!!!????

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.
