Firefox's geo.wifi.url's https://www.google.com/loc/json not used?

Question

I used a network sniffer and examined all the requests going out from Firefox when going to http://html5demos.com/geo. According to my Firefox, the geolocation service according to geo.wifi.uri entry is https://www.google.com/loc/json. However I don't see this url in any of the requests.

What am I missing?

I see it in LiveHTTPHeaders:
