Refined Prime Video is a Firefox extension designed to improve user interaction with Amazon's Prime Video service. It introduces several useful features, such as the ability to blur thumbnails and hide episode descriptions to prevent accidental spoilers. Users can easily customize these settings to suit their viewing preferences. Another significant feature is the 'Continue Watching' option, which allows users to quickly resume their favorite series without sifting through numerous thumbnails. Simply clicking the extension icon presents a list of recently watched shows, enabling seamless playback from the last watched episode.

Additionally, the extension enhances navigation with a keyboard shortcut for skipping trailers, intros, and recaps, making the viewing experience more efficient. Users just need to press the 'S' key to skip these segments instantly. The extension requires certain permissions to access Prime Video’s data, ensuring it can modify the platform's behavior effectively. This subscription-based tool is a valuable addition for avid Prime Video users looking to streamline their viewing experience.
