(Whiteboard: [Snappy])

On my slower machine we can reach XRE_main in 0.4s, createTopLevelWindow in 1.5s, but we get to firstPaint in 4.1s. We should figure out where that time is going and try to show a window sooner.

I've observed this as well. I think the addon manager work will affect this the most
