Geo-awareness:
With Firefox 3.5, a web app that wants to know where you are can now just ask Firefox. Once you provide a web app with permission to do so (Firefox’s geolocation abilities are opt-in, as they should be), the application can use the browser to determine your location.
This means developers can provide more accurate local search results and other geo-aware functionality without the user having to install any special software or having to manually enter location data, like a ZIP code.
Google and Mozilla have partnered for Firefox’s geo-aware features — the underlying code will use Google’s Location Service as its default location provider. This is the same web service that powers all of Google’s geolocation applications, including Google Latitude and the location finder in Google Toolbar.
