Session Manager is one of those apps that works wonderfully with just the default settings. The aptly called Session Manager fills this gap, allowsing you to save and restore multiple sessions. Firefox allows you to restore previous windows and tabs, but it doesn't come with an elaborate session manager.
Meanwhile, all browsers offer this feature to some extent. Restoring browser sessions was a milestone in browser development.
