browsers including Chrome, Firefox and Internet Explorer now include “geolocation” services based in the browser. What this does is attempt to locate you based on your IP, wi-fi or network location.
Geolocation is a technology that locates your position on the planet and ties it into your web browser (or other application).
Turning off the location features in either browser is fairly easy. When you are first given the chance to allow or deny location in Firefox, you can disable it right from that menu. If you have already allowed it, go to the configuration settings by typing about:config in your browser window. Find the setting geo.enabled and double click it to set it to “false.”
In Google Chrome, the settings are in chrome toolbar How To Disable Or Fake Your Location In Firefox, Internet Explorer & Chrome -> Options -> Under The Hood -> Content Settings -> Location, if you don’t find it the find in settings may help.
In Internet Explorer 9 you can also disable location services. Go into Internet options -> Privacy. Select “Never allow websites to track your physical location.”
