title: In a Chrome Extension, how would I load a URL as popup?
body: <p>I want to load a URL as default_popup, not just a static HTML page. I could load a URL with an iframe, but the issue would be that the URL that I am trying to load would not be the same always.</p>
  
  <p>Say I was on stackoverflow.com/random-url, I would perhaps want my Chrome Extension to open up google.com/<strong>stackoverflow.com/random-url</strong>, as an example.</p>
  
  <p>I'm completely new to Chrome Extensions. The best I know is to use iframes but as I said, that won't work unless I could somehow get the current URL of the tab in the static HTML file...</p>
