Here's the JS if you want to copy and paste it into a new bookmark:

• Instructions:

javascript:(function(){function getYouTubeId(url){const patterns=[/(?:youtube\\.com\\/(?:[^\\/]+\\/.+\\/|(?:v|e(?:mbed)?)\\/|.*[?&]v=)|youtu\\.be\\/|youtube\\.com\\/shorts\\/)([^"&?\\/\\s]{11})/i,/youtube\\.com\\/live\\/([^"&?\\/\\s]{11})/i];for (let pattern of patterns){const match=url.match(pattern);if (match&&match[1]){return match[1];}}return null;}const videoId=getYouTubeId(window.location.href);if(videoId){window.location.href='<https://www.youtube.com/embed/'+videoId;}else{alert('No> valid YouTube video ID found!');}})();

Here’s the code in a more readable format for the curious:

javascript:(function(){
  function getYouTubeId(url) {
    // Match patterns for different YouTube URL formats
    const patterns = [
      /(?:youtube\\.com\\/(?:[^\\/]+\\/.+\\/|(?:v|e(?:mbed)?)\\/|.*[?&]v=)|youtu\\.be\\/|youtube\\.com\\/shorts\\/)([^"&?\\/\\s]{11})/i,
      /youtube\\.com\\/live\\/([^"&?\\/\\s]{11})/i
    ];
    
    for (let pattern of patterns) {
      const match = url.match(pattern);
      if (match && match[1]) {
        return match[1];
      }
    }
    return null;
  }

  const videoId = getYouTubeId(window.location.href);
  if (videoId) {
    window.location.href = '<https://www.youtube.com/embed/>' + videoId;
  } else {
    alert('No valid YouTube video ID found!');
  }
})();
