Project Goal

Allow Mozilla to deploy experiments to a statistically-relevant population of users and measure the results.

Project Summary

With telemetry experiments enabled, Firefox will periodically retrieve a list of experiments from a secure server if the user meets the specified condition(s). Possible conditions include:

  • Product
  • Version
  • OS
  • Channel
  • Build ID
  • Language
  • Sample ratio

Each experiment will include the following information:

  • experiment ID
  • specific conditions for running the experiment
  • experiment start date & end date
  • experiment duration
  • XPI URL & hash

Test Plan

  • QA Testing Template can be found in the following etherpad: Here
  • Telemetry Experiment test plans can be found: Here

Experiments

You can view current and past telemetry experiments Here

  • Note: Some experiments that have already been expired may not be grayed out once expired when viewing the experiment list Here. The experiment is technically already disabled and once another experiment is pushed, the list will than be updated and the expired experiment will be grayed out.
