YouTube™ No Buffer is a free Chrome extension developed by tlintspr that prevents YouTube HTML5 and Flash players from auto-buffering (auto-playing) videos. This add-on is designed to save bandwidth and stop YouTube videos from buffering on multiple tabs simultaneously.

With YouTube™ No Buffer, you need to manually click on the player to allow buffering of the media files. Once a player is buffered, it can play multiple tracks without requiring activation for each new track. This makes it convenient for watching playlists and enjoying uninterrupted video playback.

The extension offers several features to enhance your YouTube experience. It stops auto-playing on "/watch?v=", "/user/", and "/channel/" pages, as well as on embedded YouTube players. It also supports YouTube's new Material Design, ensuring compatibility with the latest interface updates.

Please note that YouTube™ No Buffer is not compatible with the old non-material design, starting from versionof the extension. However, it is compatible with ad-blocker extensions operating on YouTube pages.

Overall, YouTube™ No Buffer is a handy tool for those who prefer manual control over video buffering on YouTube. It effectively prevents auto-buffering and provides a smooth playback experience.
