Remove playlist info from YouTube URL

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(0,location.href.indexOf("&list"));})();

Drag and drop to bookmark toolbar: YTNoList

Remove GCLID from Google links

Open Instagram Photo in New Tab

Open YouTube Short as regular video

YouTube Shorts do not allow you to adjust the volume, or move backwards and forwards in the video.

Note: You can also simply replace “short” with “watch” in the URL, but I found it cumbersome and prefer this one-click method.

javascript:(function(){location.href = "https://www.youtube.com/watch?v=" + location.href.substring(location.href.indexOf("shorts")+7);})();

Drag and drop to bookmark toolbar: YTNoShort
