YouTube Control Center is an open-source Firefox extension designed to enhance user interaction with YouTube.com. This tool allows users to customize their viewing experience by setting preferred playback quality and volume for all videos, controlling autoplay and autobuffer behaviors, and managing video controls. Users can also auto-pause videos when a new player starts, loop single videos, and change the video player theme.

In addition to playback enhancements, YouTube Control Center offers options to hide or show various interface elements such as video annotations, comments, views info, and action buttons. This provides a streamlined viewing experience tailored to individual preferences. As a subscription-based tool, it aims to improve the overall usability of YouTube while providing users with greater control over their video consumption.
