title: Greasemonkey simple html text replacing not working
body: <p>I need to replace all the olds links of an HTML page by the new web page so I created the following script</p>
  
  <pre><code>document.body.innerHTML.replace('www.forumoldpage','www.forumnewpage');
  </code></pre>
  
  <p>Save it but when I open the web page do nothing.</p>
  
  <p>There's something wrong with the code or do I forgot something to do?</p>
