title: Send selected text to url using context menu as Firefox add-on
body: <p>I have been doing some hours of research and trial and error on this topic but can't seem to find a decent documentation or suggestions on how to get me started in the right direction.</p>
  
  <p>What I am trying to achieve is create <strong>my own Firefox add-on</strong> which is supposed to let you <strong>select text</strong> on any given website, <strong>right click</strong> and display a <strong>context menu option</strong> to <strong>send the selection to a given website</strong>.</p>
  
  <p>Does someone have any experience with any of those issues or is able to come up with something from the top of your head?</p>
  
  <p>Much appreciated.</p>
