The problem is:

* FxA starts up with MP locked, so only partial data is read.
* FxAccountsProfile.jsm fetches the profile data, and calls setUserAccountData() with updated data.
* Now setUserAccountData has been set we've lost the data in the login manager as we haven't previously read it.

To repro, see bug 1146346 comment 20, but when the "Sync Options" pane is open (which triggers the profile code).

See also bug 1150344, which describes how we might fix this.
FTR, this test change demonstrates the underlying problem.

I opened bug 1157529 for the more general solution, but it's not clear this is going to land in time to fix this bug. Gavin suggested that we probably need to disable the profile saving code or otherwise work around the problem until a better fix is found.

Chris/Ryan/Zaach, can you guys have a chat about this and decide on what you think is the best way forward?

(NI all of you, but really it's just a single NI ;)

How about we cache profile data in memory only for now? That way it won't hit the server every time the pref pane renders.

I'll defer completely to Zach's instincts here.  Caching in memory seems like a sensible compromise in the short term.

Approved for aurora so that we don't ship 39 with this regression.
