YouTube Uninterrupted is a Firefox extension designed to enhance the viewing experience by preventing interruptions during playback. This tool effectively removes the annoying “Continue watching?” dialog that appears after a period of inactivity, making it ideal for music playlists, podcasts, and long-form content like lectures and ambient videos. With a focus on privacy, the extension is lightweight and efficient, ensuring minimal CPU and memory usage while operating without tracking or data collection.

The extension employs a three-layered approach to maintain uninterrupted playback. It uses CSS injection to hide the dialog, DOM monitoring to remove it if it appears, and simulates user activity to prevent YouTube’s idle timer from triggering. Fully open-source and available on GitHub, YouTube Uninterrupted is a practical solution for users who prefer a seamless viewing experience without the need for constant interaction.
