Ultrawide Netflix is a Firefox extension designed to optimize the viewing experience of Netflix content. This multimedia tool provides users with keyboard shortcuts to easily adjust video dimensions for a more immersive experience. Users can apply a regular zoom, stretch the image horizontally, or use a mixed version that combines both features to suit different types of content, such as series with varying aspect ratios. The extension is subscription-based, ensuring ongoing updates and support for users.

The extension operates smoothly by injecting JavaScript into the Netflix webpage, which allows it to modify video display settings directly. While it requests access to Netflix data for its functionality, it does not read any personal or private user information. This transparency in functionality ensures users can enjoy enhanced viewing without compromising their privacy.
