Comment New feature worth having (resume session) (Score 1) 564
Resuming your browsing session: The Session Restore feature restores windows, tabs, text typed in forms, and in-progress downloads from the last user session. It will be activated automatically when installing an application update or extension, and users will be asked if they want to resume their previous session after a system crash.
To activate:
Under "Options"- "Main" tab - from the drop down menu "When Firefox starts:"
select "Show my windows and tabs from the last time".
This feature is gold and alone make it worthwhile to upgrade.
