Feature Experiments

This document describes the feature experiments that are currently implemented across the Normandy project, and how to enable them.

Recipe Client Add-on

Lazy Client Classification

By default, the recipe client makes a request to an endpoint on the recipe server to calculate some info about the user that we don’t trust the client to determine, such as geolocation or the current server time. Normally, this happens on startup; enabling this experiment makes the client only make the classification request if a recipe actually uses the info for filtering.

To enable, create a new boolean preference called extensions.shield-recipe-client.experiments.lazy_classify and set it to true.
