Youtube Dislike Viewer, also known as Yt Dislikes Viewer, is a Firefox extension designed to restore the dislike count on YouTube videos. This free tool allows users to view the number of dislikes on any video, a feature that was removed by YouTube to promote positive interactions between viewers and creators. By utilizing YouTube's API, the extension provides a way for users to gauge the community's sentiment towards videos, especially useful for identifying misleading content and spam. In addition, the extension maintains a record of dislike counts for over 10,000 videos, ensuring users can access this data seamlessly.

Beyond just displaying dislikes, Yt Dislikes Viewer aims to enhance the overall YouTube experience by offering customization options. The developers are actively working on integrating additional features, including a new rating system in collaboration with Sponsorblock. This extension not only addresses a significant gap left by YouTube's changes but also empowers users to make informed decisions about the content they consume.
