How did they do that?

I just checked out Firefox 3.5's geolocation feature, expecting it to maybe get my city and it pinpointed my home address.

How does Firefox's location service know where I live? I thought it'd use my IP address and maybe figure out it was in a block assigned to customers of my ISP in my city, but it pinpointed my address exactly.

I don't expect my ISP publishes that informtion, so how the hell did Firefox know? If you're using Firefox 3.5 (or any other borwser offering Geo location services) check out what it's telling the world here.

Apparently it's Google that supplies the information, Firefox just hands reponsibility for Geo location requests to pre-configured providers of such information. By default that's Google.

So how does Google know where I live? Is this an exampe of data mining and matching disparate information found on websites with activity from my IP?

That would be worrisome. But according to Google that's not how it's done. It apparently uses information gleaned from Wireless access points seen by my notebook.

But thinking about this still worries me - exactly when did a piece of software on my PC access Wifi information and send that info to Google, attached to my IP?

I suppose it was when Firefox asked me if it could pass Geo-location on.

Firefox was thoughtful enough to let me know when a site asked for Geolocation information. How many other applications will be so kind? I don't think there's anything in my operating systems structure that protects whatever interfaces Firefox thought to ask to use to glean geolocation revealing information.

I wonder how long it'll be until sites check outs are pre-populated with delivery details, even befroe you tell them anything?

And how does sniffing Wifis provide that information in the first place? There's no business WiFi near me broadcasting loction infomation, only my own and neighbours Wifi. Did Google sniff Wifi station identities at the same time they drove by to produce street views?
