BlockTube is a Firefox extension designed to enhance your YouTube viewing by allowing users to block unwanted content such as specific channels, videos, and comments. This lightweight tool integrates seamlessly with the YouTube interface, ensuring that it does not disrupt your browsing experience. Key features include the ability to block videos and channels by name, filter comments based on keywords, hide watched videos from recommendations, and remove annoying popups. Users can also manage the visibility of YouTube Shorts and Movies, as well as control the Explore page and auto-generated playlists.

For advanced users, BlockTube supports regular expressions across all filtering options, providing a customizable experience tailored to individual preferences. The extension prioritizes user privacy, as it does not collect any personal data or utilize tracking codes, with all configurations stored locally on the user's device. This ensures a secure browsing experience while effectively managing YouTube content.
