CloudServices/Location
Objective
The objective of this project is to produce a Minimum Viable Product (MVP) version of a Location Service.
FAQ
Every project has some frequently asked questions. We also have a short about page and a dedicated privacy policy.
Summary
The "Mozilla Location Service" project is a pilot project to assess the impact Mozilla can have on the geolocation landscape, specifically to improve user privacy and enable innovation by creating public data sets. In order to do this assessment, we need to understand the technological challenges and get real data. Therefore, the Services team will build and operate a location service to provide geolocation lookup for devices, based on cell tower, Wi-Fi or IP address information.
Geolocation lookup is a very useful service to provide to users. There's no public data set to provide this service. None of the current companies offering this type of service have any incentive to improve on privacy. Geolocation lookup and the potential for tracking the physical movement of individuals is a serious privacy issue.
Why Mozilla? The web platform needs the capability, and currently we have to provide it in our offerings through business deals without much impact on the privacy aspects of the service. We have a unique access to Firefox on lots of devices for gathering and reporting back data. We don't have to monetize the gathered data and can make it available to the public. If we can run a successful service, we get leverage to improve the privacy aspects in the landscape.
For more information about user privacy, see "Privacy". We are also maintaining an "overview of existing data sources".
Goals
- Location Service Roadmap
- Provide a highly accurate geolocation service for any device and in any country, based on publicly sent signal information (like cell towers, Wi-Fi, IP addresses).
- Improve the privacy aspects of the geolocation service compared to the current market offerings.
- Make as much of the data as possible available under permissive open licenses.

Bug reporting
- Bugs can be reported in the general Bugzilla tracker under the Mozilla Services :: Location component (for legal, operations, or unknown category)
- A list of open bugs: Location bugs
- If the bug is about the stumbler of server code or has a patch / pull request associated with it, you can use the github bug trackers for the two projects.
Meetings
The team holds a weekly meeting to discuss location client and server development:
- Time: Thursday at 10:00AM PDT / 13:00PM EDT / 6:00PM UTC.
- Place: Vidyo room #geolocation (9429)
- Phone (US/Intl): 1 650 903 0800 x92 Conf: 9429#
