Firefox Remote Settings

Remote Settings is a Mozilla service that makes it easy to manage evergreen settings data in Firefox. Firefox/Kinto is used for syncing of data. A simple API is available in Firefox for accessing the synchronized data.

Key Features

• Admin UI (generated from data schema)
• Data history
• Preview data (QA)
• Sign-off (review)
• File attachments
• Email notifications
• Content signature (Autograph integration)
• Single endpoint for polling for changes
• Client synchronization (diff based, local db)
• Client-side target filtering (JEXL a-la Normandy)
• Client Telemetry
• Robust protocol (retry, precondition headers, backoff, …)

const { RemoteSettings } = ChromeUtils.import("resource://services-settings/remote-settings.js", {});

RemoteSettings("my-collection")
  .on("sync", (e) => {
    // e.data.current = [ Record, Record, ... ]
  });
