For once, it's Chrome that is playing catchup with Firefox as tab sync has been in Firefox for a long time. But here it is, :self::Chrome stable is now at version 19:. Here's an extract from the "Chrome Releases" blog:

Chrome 19 Stable Channel Update
"The Google Chrome team is happy to announce the arrival of Chrome 19 to the Stable Channel for Windows, Mac, Linux and Chrome Frame. Chrome 19 contains a number of new features like tab sync. More detailed updates are available on the Chrome Blog."

The final version of :self::Firefox 12: is ready for Ubuntu users in the Ubuntu Mozilla Security. The release notes are pretty short and that's because there are few changes for non Windows users.
