The Mozilla Location Service

The Mozilla Location Service provides geolocation data based on cell tower and WiFi access point information. Mobile phones with a weak GPS signal and laptops without GPS hardware can use the service to quickly identify an approximate location.

You can see where the service is available on the new Mozilla Location Service Coverage Map. The map was created with MapBox and uses a dark variation of Mozilla’s custom maps, using Mozilla's typography for the map labels. A pretty neat feature of the map is how the labels are layered on top of the blue data points so that users can still easily navigate the map.
