Problem

The current process of timing the launching of Firefox OS applications is tricky. At the time of writing, most tests rely on the firing of the window onload event in order to determine when it is ready to use. Unfortunately with the state of dynamic script and view loading, it's impossible to tell when an application is truly ready to be interacted with. The loading of these assets can be deferred, sometimes even to the point where it occurs after window onload. If we want to hold an application accountable to recommended launch times, engineers need only defer more loading until the test measurement completes in order to make metrics look attractive. Couple this with the fact that the event isn't truly indicative of user interactivity and you can see that the current state is unsustainable.

Interim Solution

I suggested that if we were to get an accurate pulse on when launch times occur, it was going to take being told by the application itself. There are techniques we can use to try
