About

This is the home page for development of the Sync client bundled with the Firefox and Fennec browsers.

Starting with Firefox 4, Sync is bundled by default with Firefox. In previous versions of Firefox, Sync was available only as an add-on. Upgrading to Firefox 4 should be a seamless process.

Status and Planning

Our full roadmap is available at roadmap.

In-Progress Work

Setup Improvements on Desktop

Significant changes are being made to the setup experience on the desktop to make it easier to use and understand.

Development Info

Source Code

Assuming you followed the instructions at Getting Started, you should have a copy of mozilla-central or services-central available.

Sync code lives in the following locations inside these repositories:
