CloudServices/Sync/FxSync

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.
