title: Streaming website data into Excel with VBA
body: <p>A website provides streaming stock quotes via a browser over HTTPS connection. This is done by the server sending a POST HTTP header and updating its body with the new quotes. The DOM is then updated and this then translates into visual updates. I want to get these quotes, preferrably streaming as well, into Excel. I may use only VBA, .NET framwork, and firefox add-ons.</p>
  
  <p>I am stuck over how to do it. I am limited to VBA and .NET and Firefox add-ons. What libraries, objects, firefox add-ons would you advise me to use?</p>
