WebExtension API for Telemetry

Use the browser.telemetry API to send telemetry data to the Mozilla Telemetry service. Restricted to Mozilla privileged webextensions.

Types

ScalarType

Type of scalar: ‘count’ for numeric values, ‘string’ for string values, ‘boolean’ for boolean values. Maps to nsITelemetry.SCALAR_TYPE_*.

ScalarData

Represents registration data for a Telemetry scalar.

Properties:

  • kind - See ScalarType.

  • keyed - (optional, boolean) True if this is a keyed scalar. Defaults to false.

  • record_on_release - (optional, boolean) True if this data should be recorded on release. Defaults to false.

  • expired - (optional, boolean) True if this scalar entry is expired. Operations on an expired scalar don’t error (operations on an undefined scalar do), but the operations are no-ops. No data will be recorded. Defaults to false.

EventData

Represents registration data for a Telemetry event.

Properties:

  • methods - (array) List of methods for this event entry.

  • objects - (array) List of objects for this event entry.

  • extra_keys - (array) List of allowed extra keys for this event entry.

  • record_on_release - (optional, boolean) True if this data should be recorded on release. Defaults to false.

  • expired - (optional, boolean) True if this event entry is expired. Recording an expired event doesn’t error (operations on undefined events do). No data will be recorded. Defaults to false.

Functions

submitPing

browser.telemetry.submitPing(type, message, options);

Submits a custom ping to the Telemetry backend. See Submitting custom pings.

  • type - (string) The type of the ping.

  • message - (object) The data payload for the ping.

  • options - (optional, object) Options object.

    • addClientId - (optional, boolean) True if the ping should contain the client id and profile group id. Defaults to false.

    • addEnvironment - (optional, boolean) True if the ping should contain the environment data. Defaults to false.

    • overrideEnvironment - (optional, object) Set to override the environment data. Default: not set.

    • usePingSender - (optional, boolean) If true, send the ping using the PingSender. Defaults to false.

canUpload

browser.telemetry.canUpload();

Checks if Telemetry upload is enabled.

scalarAdd

browser.telemetry.scalarAdd(name, value);

As of Firefox 134, this method is a no-op. See Bug 1930196.

Instead, use Glean APIs to record scalars.

scalarSet

browser.telemetry.scalarSet(name, value);

As of Firefox 134, this method is a no-op. See Bug 1930196.

Instead, use Glean APIs to record scalars.

scalarSetMaximum

browser.telemetry.scalarSetMaximum(name, value);

As of Firefox 134, this method is a no-op. See Bug 1930196.

Instead, use Glean APIs to record scalars.

recordEvent

As of Firefox 132, this method is a no-op. See Bug 1894533.

Instead, use Glean APIs to record events.

registerScalars

browser.telemetry.registerScalars(category, data);

As of Firefox 134, this method is a no-op. See Bug 1930196.

Instead, use Glean APIs to record scalars.

registerEvents

As of Firefox 132, this method is a no-op. See Bug 1894533.

Instead, use Glean event definitions for your extension’s events.

setEventRecordingEnabled

As of Firefox 133, this method is a no-op. Event recording is enabled by default unconditionally. See Bug 1920562.

Instead, use Glean event definitions for your extension’s events.
