Firefox Sync
Firefox Sync, originally branded Mozilla Weave, is a browser synchronization feature for Firefox web browsers. It allows users to partially synchronize bookmarks, browsing history, preferences, passwords, filled forms, add-ons, and the last 25 opened tabs across multiple computers. The feature is now included in Firefox and is being implemented in Thunderbird.

It keeps user data on Mozilla servers, but according to Mozilla 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 Sync was originally an add-on for Mozilla Firefox 3.x and SeaMonkey 2.0, but it has been a built-in feature since Firefox 4.0 and SeaMonkey 2.1.
Firefox Sync is built on top of Firefox Accounts as of Firefox 29, and therefore Firefox 29 and later cannot sync with Firefox 28 and earlier.
