FHR needs access to a certain set of profile information that's hard to get outside of Gecko. Add-ons is one main culprit (Bug 865444), but there's also blocklist and telemetry prefs, and the profile creation time (for which code already exists in JS, but not in Java).

The simplest and most performant solution for this seems to be to dump these values from Fennec after Gecko startup, store them in a single file written in the background, and to load that file lazily when needed.

This bug tracks doing so.

nit: this is way too generic a name.  "profile_info_cache.json"?
