-/**
- * Session Storage and Restoration
- *
- * Overview
- * This service keeps track of a user's session, storing the various bits
- * required to return the browser to it's current state. The relevant data is
- * stored in memory, and is periodically saved to disk in a file in the
- * profile directory. The service is started at first window load, in
- * delayedStartup, and will restore the session from the data received from
- * the nsSessionStartup service.

- * Session Storage and Restoration
- *
- * Overview
- * This service keeps track of a user's session, storing the various bits
- * required to return the browser to it's current state. The relevant data is
- * stored in memory, and is periodically saved to disk in a file in the
- * profile directory. The service is started at first window load, in
- * delayedStartup, and will restore the session from the data received from
- * the nsSessionStartup service.
