Summary

Welcome to the developer home of Firefox Sync. For end-user (non-technical) information, please see the official Sync web site.

Firefox Sync is a set of software components and specifications that synchronize data between multiple Mozilla product instances. The software is open source and the specifications are all public. This means that others are free to implement components or run the software on their own.

Products and Services

The Sync family consists of the following products and services:

Client integrated in the Firefox and Firefox Mobile browsers
Server 
Server component used for cross-client communication
Firefox Home 
An iOS application (iPhone, iPad) that allows you to view Sync data from these devices
Server Instance 
A Sync server operated by Mozilla available for use by anybody in the world, free of charge. This is where Firefox sends data by default, unless you specify a different server.

Specifications

The Specifications of Sync cover:

HTTP API 
Implemented by the Sync Server. Used by clients to exchange data
Cryptography Model 
How encryption is used to securely store data in the Sync Server (the Sync Server can't even read important data)
Data Storage Formats 
How existing clients (like Firefox) format synchronized data
Client APIs 
These include the JavaScript API available in Firefox

Device Manager
  • Problem
    • Currently sync uses the 'clients' sync data collection as a list of active devices. This list has no state and difficult to 'delete' an device off list. Most client display a device if it's been active within the last two weeks. This design creates a number of bugs visible to the user.
  • Plan
    • All devices, Desktop, Android, iOS register with FxA
    • There should be events that removed devices from this list, such as uninstall, reinstall, or devices with the same name conflicts.
    • FxA device manager endpoint provides real-time list of active devices to sync clients to display.
  • FxA device manager *WIP*
  • Github Issue in Waffle board
  • Feature Document
  • Current Status
    • Pending device registration on iOS and fixing issues - bug 1250783 - active WIP
    • Pending fixes to settings display
    • Pending work to improve the accuracy of the device list controlled by user events.
    • Pending management UI of devices.
