FD needs to talk to Add-on Builder Helper extension. It uses its API to

1. install add-on
2. uninstall add-on
3. check if Helper is installed
4. listen to document.body.addonbuilderhelperstart

Installing Add-ons

If the Helper is installed hitting Test should simply install add-on

 if (window.mozFlightDeck) {
   FD->createAndDownloadXPI // using currently displayed content
   window.mozFlightDeck.send({cmd:"install",contents: downloadedXPI})
 }

Else display the warning with ability to install the Helper. Listen for the event fired after its installation and try to install add-on again. The listening for the event should be cancelled after some time or after certain action.

 if (!window.mozFlightDeck) {
   FD->displayWarning
   // listen for the event
   $(document.body).addEvent('addonbuilderhelperstart', function() {
     FD->displayNotification
     FD->installAddOn
   });
   // stop listening after some time
   (function() {
     $(document.body).removeEvents('addonbuilderhelperstart');
    }).delay(someTime);
 }
