The popular Google Browser Sync extension for Firefox, which synchronizes browser settings and information across multiple computers, is now an open source project. Google is distributing the Browser Sync source code under the BSD license and is making it available through a Subversion source control repository on the Google Code website.
This is a major reversal of Google's position on Browser Sync, and it will very likely save the add-on from extinction. Shortly before the official launch of Firefox 3, Google said that Browser Sync development would be discontinued and encouraged users to adopt Mozilla Weave or Foxmarks instead. The availability of the Browser Sync source code, however, will make it possible for the open source software community to collaboratively bring the add-on to the new version of Firefox.
Please, somebody who's smarter than me, take the open source and make it work for FF3!
