The initial request is the GoogleURLTracker class, which manages what Google TLD you're on. On the trunk, this won't happen if your default search engine is not Google, and even if it does happen, we won't save/update any cookies as a result of the update request.
Also, the reporter is using a binary downloaded from the continuous builder, that's why RLZ is included.
