Youtube has removed dislike statistics. This extension return this functionality back. My project is similar to other ones, but with some features that was important personaly for me : - Support select of "dislikes" data providers, so you can clearly see where "likes\dislikes" stat was loaded from. You can find decription of data sources in extension settings. - If you want to see data source directly on youtube page check that option in [Addition oprions] -> [Display data source in ratio bar popup] is activated (activated by default in new versions, since 1.1.1.8) - Custom ratio bar that can be disabled or recolored from extension settings - Partly compatible with some mobile browsers (install instructions depends on browser version - read more) Currently supported data providers : - YouTube metadata parsing (used by default, helps to detect original likes count \ is video votes closed) - API by Return YouTube Dislikes (https://returnyoutubedislike.com/) - active by default. Currently most effective. Used archived youtube data and votes from users of extensions \ services that support this API. By default extension sends like \ dislike actions to this API to keep stats updated (usually data applys after 2-3 days). You can disable send actions if needed for some reason in extension options. - API by SponsorBlock (Documentation) - Currently disabled by default. Not many extensions used it currently, so there is almost zero data for current time. - API by CatFace (my server, currently used as small historical data archive) Extension source code is available on GitHub How extension count "dislikes" and is this results accurate?
