title: Greasemonkey get names of all open tabs
body: <p>My ultimate goal is to have an autocompleting list that displays all open tabs (in Firefox), which I can reduce to the tab I want to switch to next.</p>
  
  <p>I can do the completion / combobox etc, but I don't know how to get the list of all names (and favicons wold be a huge bonus). Would be grateful for any pointers.</p>
