BBViewer is a specialized Firefox extension that significantly improves the video viewing experience, particularly for fans of Big Brother US Live Feeds. This tool offers a custom video player interface that provides enhanced functionalities like a fullscreen mode, Picture-in-Picture (PIP) support, and adjustable playback rates for websites that do not have these features built-in. Users can easily switch between aspect ratios and modify audio settings, including panning and gain boost, to tailor their viewing experience to their preferences.

Furthermore, BBViewer includes a sidebar with built-in chat and interactive tools for supported websites, making it a more immersive platform for users. The extension also supports various themes and offers enhancements specific to the Paramount+ Live Feed page. However, it is essential to note that access to the Big Brother Live Feeds requires a Paramount+ subscription, and BBViewer operates independently from Paramount, CBS, or Viacom.
