title: Autofill a form of another website and send it
body: <p>I searched the web and found nothing.</p>
  
  <p>On the website, there is a Input box for a E-Mail address. I would like to fill this field with an e-mail address and the send the form. Then i will get the whole source code from the website.</p>
  
  <p>I <strong>don't</strong> wanna give this to the URL like "?myvar=test&amp;myvar2=test2". I searched for examples for CURL, but found nothing.</p>
  
  <p>I only want fill the form, send it, and get the source code. Or is there an addon for firefox or a free program?</p>
  
  <p>With best regards
  KalTo </p>
