Does not work for me at all. (firefox) If I go to a new youtube video with little or no likes/dislikes and click thumbs down I can clearly see it give a thumbs up instead. Has been doing this almost as soon as this came out. I think this is a scam probably by youtube to make people THINK they are giving thumbs down but actually giving thumbs up.

Works better than expected.

Completely inaccurate.
I talked with a content creator on a video which had over 40 downvotes counted through this addon, but through the YT backend it only shows 4.

I could understand if the addon counted LESS downvotes than what there are in reality, but it seems like it shows either random garbage or there's ways to manipulate the vote count.

Either way, it is inaccurate to the point of being completely useless.

hilarious. works perfectly. can't believe youtube ever removed dislikes.

Seems to work ok. Except if the owner of the video disables like/dislike buttons (I think that's the problem). Then I can't click the Save button to add the video to a playlist. I needed to disable this add-on to enable the Save button. I would submit this as a bug report but I can't find that option anywhere. Doing a review instead.

worked great until it didn't

Worked great until it stopped working. Can't get it fixed. Oddly only works in incognito tabs now.
