The Geo-location API lets you share your location with trusted web sites. The latitude and longitude are available to JavaScript on the page, which in turn can send it back to the remote web server and do fancy location-aware things like finding local businesses or showing your location on a map.
As you can see from the following table, the geolocation API is supported by most browsers on the desktop and mobile devices.

- Firefox 3.5+
- Safari 5.0+
- CHROME 5.0+
