YouTube no Buffer no autoplay is a Firefox extension that enhances video playback on YouTube by preventing auto-buffering, allowing users to manage bandwidth more effectively. This tool is particularly useful for those with limited data plans or who often have multiple tabs open, as it requires a manual click to start buffering, ensuring only the desired content is loaded.

In addition to stopping auto-buffering, the extension also halts auto-playing videos across various YouTube interfaces, including user profiles and embedded players. It is designed to work with YouTube's latest Material Design and is compatible with ad-blocker extensions. Users can customize their settings to ensure smooth playback without interruptions, making it a practical solution for a controlled and efficient YouTube viewing experience.
