Comment:

 My HIPS detected that TBB is using RPC / DNS Client Service on Win (and
 similar caching facilities of other OSes) during initialization. It can be
 that FF fetchs something from DNS cache in early stages (hardcoded) or
 not. But TBB is definitely not required this common FF's RPC/other
 "channel" to system DNS services.
