Latest night build of Firefox has got another pending feature, synchronization of add-ons across multiple computers. As we reported earlier on BrowserFame, Firefox team is working on it for long, and it will appear in the stable channel with Firefox 11 or Firefox 12.
Currently, Firefox allows users to sync their bookmarks, passwords, browser history, tabs and preferences. This upcoming feature will allow users to synchronize their add-ons across multiple Firefox installations.
Update: This feature is now live in Firefox 11.
