title: Which Browser/IDE for rapid add-on development/prototyping?
body: <p>I'd like to develop an extension for a browser which does the following.</p>
  
  <p><em>Prerequisite:</em> Text has been selected, add-on has been triggered (e.g. by click in context menu)</p>
  
  <ul>
  <li>read selected text</li>
  <li>pass the text to a (e.g. RESTful) webservice</li>
  <li>retrieve a list of comments from the webservice</li>
  <li>show them in the browser</li>
  <li><em>optional:</em> show also an input field below to send another comment to the webservice</li>
  </ul>
  
  <p>Writing a Firefox add-on became quite annoying since I haven't found a proper documentation and IDE (with a handy build process).</p>
  
  <p>Which Browser/IDE combination do you recommend for rapid add-on development/prototyping?</p>
