Removes the playlist information from a YouTube URL. When you watch something from a playlist, or just the Watch Later list, you may not want to automatically skip forward to the next video. This bookmarklet will strip the playlist info from the URL and reload the page.

javascript:(function(){location.href = "" + location.href.substring(location.href.indexOf("shorts")+7);})();

Drag and drop to bookmark toolbar: YTNoShort
