For the FxAccounts.jsm module (bug 909967), if a user shuts down the browser in the middle of the email verification process, we need to do the right thing when the browser is started up again. How should the verification process be started again? Should it: a) be triggered when the browser starts? (This is what it does now, and it seems a bit ungainly) b) be triggered when getSignedInUser returns an unverified identity? (Makes the caller pay for it) c) be placed on some kind of "nice" queue for deferred execution after browser start-up is complete and the dust has settled (is there such a thing?) d) something else?

(Makes > the caller pay for it) FWIW, this is actually what FxAccountsManager does with getAccounts. If I am not wrong, we only need the information about a verified account when: 1- we want an assertion 2- we want to show the account details For B2G, in both cases, we use FxAccountsManager.getAccounts that requests the verification status if the account is not yet verified. Take a look at [1] and [2].

Jed, I think I am satisfied with the current behavior of b). We can let the product owners decide otherwise. Are you OK with marking this resolved/works for me?
