Crash Analysis
+ +Finding new and rising crashes
+Analyze crash data to help developers to debug and fix crash issues
+Only voluntarily submitted crashes
+Telemetry
+ +Anonymized data from very specific probes, e.g. startup time, crashes experienced, number of bookmarks, etc.
+Environment, e.g. OS, graphics hardware and drivers, add-ons, etc.
+2 sets of data: base (formerly FHR) + extended
+Telemetry: Examples
+ +Telemetry Experiments

+Examples: e10s (right now), default search (late 2014)
+UI Telemetry
+ +Telemetry about usage of UI elements
+Example: items in toolbar vs. menu panel vs. customize mode
+Android: +initial findings, +url suggestions +
+Website A/B Testing

+Examples: Fundraising, many others
+User Studies
+ ++with more invasive telemetry,
+small set of users included
+are informed and compensated. +
