Mobile/Metrics
< Mobile
This page explains the different tools available to analyze data about how people use Firefox for Android and iOS. Most of these tools currently only support Android, but eventually there should be more support for iOS.
Note: some metrics are only available to employees and may require sign-in.
Usage Metrics
Dashboards
- Adjust: Third-party SDK initially added to track install referrers, but currently our most trusted source of usage numbers. Also used to track retention.
- ADI dashboard: Gives us more granular daily use numbers per release version. Very old way of collecting usage numbers, based off blocklist pings.
- Executive metrics: Mostly not useful since we removed FHR.
- iTunesConnect: Apple's metrics tools for iOS apps. Provided detailed information for installs, daily users, retention, etc. Some measures are "Opt-In" only.
Telemetry
Our telemetry systems are currently in flux, but we are working towards a unified telemetry data pipeline to measure sessions and events. We have two levels of telemetry, opt-out and opt-in, which are controlled by data sharing preferences in our settings UI. Opt-in telemetry is enabled by default up to beta, but is really opt-in on release.
- Telemetry docs: Some of this is used on both desktop and Android, but some of it is specific to desktop only. Use caution when reading these docs in a mobile context.
- re:dash via SQL: Handy tool for performing analysis against telemetry data. Right now this only includes opt-in telemetry data.
- Self-serve telemetry analysis: Older, more hardcore tool for doing telemetry analysis.
- UI telemetry: Mobile-specific UI telemetry implementation. You can query this data with re:dash, or look at the UI telemetry dashboard.
- Core ping: New opt-out telemetry ping that we're working on to replace FHR.
- Histogram dashboard: Histogram probes are used mostly for engineering metrics. They are not as useful for product decisions, and we may stop sending histogram telemetry data on mobile.
Stability and Performance
Dashboards
- Crash stats: Where we monitor crashes.
- Perfherder: Charts to monitor memory use, build times, and APK size.
- Autophone: Startup performance tests.
