After turning my computer on, Firefox loaded and I chose the option to upgrade to version 4. I was forced to close the previous version including the session restore tab. After executing version 4, I was not provided the option to restore the previous session tabs from the last version.

Restore Previous Session is listed under the History tab but it is not an active option. I suspect that version 4 is not able draw session data from previous versions.
