title: How to have a Firefox Devtools inspector like feature for Firefox addons?
body: <p>For ex: I want to see which parts of the html code correspond to a specific element of a website, I would right-click on the element and open <code>inspect element</code> and devtools would show me the corresponding code highlighted. How do I achieve a similar result for Firefox addons because when I right click on the extension there's no such option of <code>inspect element</code>. </p>
  
  <p>I have also tried to use the <code>inspect</code> option which we get by temporarily loading an addon but still it doesn't show us/highlight which parts of the extension the corresponding html file refer to. 
  Is there a way to do so?</p>
