In Firefox 3 I used the Session manager extension to make groups of tabs, that auto-save if I exit Firefox. This makes it easy to separate each project's tabs, and switch between them fast.

Firefox 4 comes with the tab groups function, which seems to do about the same thing, but with a better interface. What are the main differences between these two, which one is technically better?
