Mozilla notes on its official Mozilla Wiki site that Telemetry is "helpful for Mozilla's engineers and decision-makers" as it is used to "measure how Firefox behaves in the real world".

Telemetry provides Mozilla with "performance and usage info". Firefox collects only "non-personal information" such as "performance, hardware, usage, and customizations" according to Mozilla.

Mozilla is more open about the Telemetry that it collects. Anyone may open the Telemetry portal to check out some of the data. The Firefox Public Data Report for example provides a weekly view of activity, behavior, and hardware configurations of Firefox users.
