title: Is there a way to get list of errors in chrome/firefox which happened throughout the web page
body: <p>I have an html file which may contain many <strong>img</strong> tags and also it will have JS like below.
  <a href="https://i.stack.imgur.com/8xqT4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8xqT4.png" alt="html file"></a></p>
  
  <p>If I try to load this page in chrome and also click the button <strong>clickMe</strong> I get the below errors in console.<a href="https://i.stack.imgur.com/axEyL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/axEyL.png" alt="error file"></a></p>
  
  <p>I know that using <strong>window.onerror</strong> I can handle/capture ReferenceError and may be save it for later. But, is there any error stack from where I can get all the list of errors which has happened during the life-cycle of the web page. Because, I am not able to capture <strong>ERR_FILE_NOT_FOUND</strong> error.</p>
  
  <p>Please let me know whether it is possible and if so how ?</p>
