The new Safari 6 Developer Preview that was available for developers shortly after the WWDC conference includes many new features from Safari 5.1 and 5.2. The move to Mountain Lion also means that Safari 6 is closer to the iOS version of Mobile Safari than ever before. Features such as iPad style tabs, iOS style expose tab navigation, and tabs that sync between iOS and Safari 6 are all welcome features being added to this version. Be aware that this is a developer preview so crashing will occur often and it is best to stay on Safari 5.2 which can be found here.

Anyways, if you want to give the new Safari 6 Developer Preview a try, you can download it from here. No guarantees of how well it will run on your system.
