title: Is it possible to modify a Web page's source and reload that page not from the server but from the edited source?
body: <p>Just a stupid question. I know it's not possible but I'm just asking a confirmation simply out of paranoia.</p>
  
  <p>It's not possible to edit the source of a Web page and somehow reload that edited script in the browser, correct?</p>
  
  <p>Otherwise, anyone could just put whatever they wanted into any page's source and reload their edited source to do whatever they liked, which would render the whole World Wide Web vulnerable.</p>
