|

|

* Crash Detection
|

* The session file stores a session.state property, that

* indicates whether the browser is currently running. When the browser shuts
|
||||
* down, the field is changed to "stopped". At startup, this field is read, and
|

* if it's value is "running", then it's assumed that the browser had previously
|
||||
* crashed, or at the very least that something bad happened, and that we should
|

* restore the session.

*
|

|

* In the event that a restart is required due to application update or extension
