Firefox Sync, originally branded Mozilla Weave, is a browser synchronization feature that allows users to partially synchronize bookmarks, browsing history, preferences, passwords, filled forms, add-ons, and the last 25 opened tabs across multiple computers.
It keeps user data on Mozilla servers, but the data is encrypted in such a way that no third party, not even Mozilla, can access user information. It is also possible for the user to host their own Firefox Sync servers, or indeed, for any entity to do so.
Firefox Home is a companion application for the iPhone and iPod Touch based on the Firefox Sync technology. It allows users of either device to access their Firefox browsing history, bookmarks, and recent tabs. It also includes Firefox's "Awesomebar" location bar. Firefox Home is not a browser; the application launches pages in either a Webkit Web viewer or in Safari. Mozilla pulled Firefox Home from the App Store in September 2012, stating it would focus its resources on other projects. The company subsequently released the source code of Firefox Home's underlying synchronization software.
