A small Firefox extension that remembers an optional Fill Ultrawide choice for each SkyShowtime title.
SkyShowtime can deliver a cinematic movie inside a 16:9 video stream with encoded black bars. On an ultrawide monitor, Fill Ultrawide applies object-fit: cover !important to SkyShowtime's video element only, which crops those outer bars and fills the player. It does not resize the player container, subtitles, or controls.
