Fullscreen Fill redubbledD מאת

Fullscreen Fill stretches landscape videos to fill your entire 21:9 or ultrawide screen instead of leaving black bars.

It stretches the video without zooming or cropping, so the full image remains visible.

Works with HTML5, MSE, DRM-protected players, and players inside iframes.
Portrait videos are never stretched.
Small previews and thumbnails are left unchanged.
Disable it for specific pages, domains, or player types.
The popup shows the detected player type and whether widescreen mode is active.
Supports English, Dutch, German, French, and Spanish with automatic language detection.
