I had pretty much lost all hope on this. I am astounded by your ingenuity, Shane, as always.
I'm looking forward to finding out how you're pulling this off. When I sign in with
eyedee.me on device (using the UI Tests page), b2g throws a CSP error:
E/GeckoConsole( 7656): Security Error: Content at
https://eyedee.me/ may not load data from
https://all-together-now.personatest.org/sign_in#NATIVE.
But it goes ahead and logs me in anyway with an assertion issued by
eyedee.me. Wha???
