Queue Playback Guard by TGuimaraes07

Queue Playback Guard provides additional playback and visual controls for supported websites.

On YouTube, it prevents automatic advancement to the next video in queues and playlists, blocks end-of-video navigation paths, disables autoplay and Picture-in-Picture, and restricts seeking near the end of videos.

The extension also applies visual filtering rules to selected interface elements on YouTube, Telegram Web, and Instagram. YouTube visual filtering follows a predefined weekly schedule, while Telegram and Instagram filtering remains active continuously.

All functionality runs locally in the browser. The extension does not collect, transmit, or sell user data and does not use analytics or remote code.
