It does seem a bit strange that they've implemented a fantastic feature and not included one preference for what could be the major use of the feature. Luckily there is a quick preference change you can make. Open up about:config. Right click, New > Boolean.
Preference Name: browser.sessionstore.resume_session
Preference Value: true
The next time you close Firefox 2.0 and open it up again all your tabs, scrolling, the contents of forms, histories and cookies will still be there as it was last time. It even works with TinyMCE which is pretty impressive!
I do see a problem in this feature in that cookies which only last for one session will never be deleted as the session is restored every time the browser gets restarted. It's probably issues such as this which stop Session Saving being included as an option in the Options window.
