title: Youtube Blob urls don't work in browsers but in src
body: <p>I know that there are no blob urls only objects.<br>
  I made my own blob object for a video buffer and then I used it in a src of video tag which is something like <em>blob://website.com/blablobbla</em> . I opened this url in the browser it worked </p>
  
  <blockquote>
    <p>when I opened the url of youtube video src (blob url) into a new tab it did't work but mine video src (blob url) worked</p>
  </blockquote>
  
  <p>I want to know how can I do the same with my blob urls so that they only work in the src of the html video tag and give error or don't work in the external tab/window of the browsers.I just want to know the technology behind this and blob objects and their url properties.<br></p>
