Aggregated information on the Firefox user population (including hardware, operating system, and other usage characteristics) is available at the Firefox Public Data Report portal.
In addition, a set of curated datasets are available to the public for research purposes. See the public data cookbook for more information.
Access to other Telemetry data is limited to two groups:
- Mozilla employees and contractors
- Contributors who have signed a non-disclosure agreement, have a sustained track record of contribution, and have a demonstrated need to access this data
If you are an employee or contractor, you should already have the necessary permissions.
If you are a contributor and want to request access to Firefox Telemetry data, file a bug in the operations component and ask an established Mozilla contributor or employee to vouch for you.
