Firefox supports Geolocation Service

Posted by Channy Yun

Firefox 3.5 Beta 4 and higher starts to support W3C’s Geolocation APIs developed by based on Gears Geolocation API. It offers your privacy information such as IP address of your PC or Wi/fi to Google server for recognizing your position under only your agreement.

You can see it simple demo.


If you have GPS enabled device, geolocation returns your location directly to web sites. This is very useful in mobile web service to find coffee shop, restaurant and friends via iPhone and PDA with GPS. But, if you don’t have this kind of device, Firefox sends your information to Geolocation service providers as like Google and get your position from its server.

Firefox doesn’t save your information or send them to any other 3rd party. If you grant to get your position, your location informations may be sent to your web site as well Google’s geolocation server. But, Firefox also doesn’t send the informaton of web site that wants to get your position to Google.

Firefox user can change default setting for Geolocation service from Google to another 3rd party that supports W3C Geolocation APIs. You type “about:config” in address bar and change “geo.wifi.uri” from “” to another. Now there is no services to do.

For more information, please refer to Geolocation in Firefox

There is my concern for privacy. I knew there was a heavy privacy discussion in WWW2009 and refer to Privacy Diffusion on the Web: A Longitudinal Perspective that shows Google has been the strong collector by their family’s cookie and javascript.

Google’s Geolocation service means that Google can collect and organize user’s information related to position such as GPS position, personal profiles such as address, mobile information to get correct IP-address database. In my experience, the user profile can make probabilistic database between IP address and real address. Google can be real big brother?
