This browser extension provides a simple way to open any YouTube video or playlist (including videos and playlists embedded in other sites/pages) in a configurable "popout" window which you can freely position and resize.
When a video is in a queue there are two options: Open Video in Popout Player and Open Playlist in Popout Player.
The latter option would understandably try to open the video with the queue playlist, although it fails because queues are not supported.
The former option triggers the same "This video is unavailable" error, although it is supposed to open without playlist, simply by omitting everything in the URL from &list= onwards.
