Auto HD + Buffer / Speed HUD on a watch page |
One-click settings popup |
- Single Playback — Only one YouTube video plays across all your tabs. A video takes over only when you actively click play; opening videos in background tabs won't interrupt what you're watching, and switching to a non-YouTube tab keeps your current video going.
- Auto HD + FPS — Automatically set your preferred resolution (up to 4K/2160p) and frame rate on every video, with optional fallback to the next best quality.
- Disable Picture-in-Picture — Block the PiP button and the PiP API.
- Theater Mode — Always start videos in the wide theater layout.
- Autoplay control — Mirror YouTube's "autoplay next" toggle to your preference.
- Buffer + Speed HUD — Optional live buffer health and download speed in the player control bar, with zero extra network usage.
