- /**
- * nsIObserver topics for profile changing. Profile changing happens in phases
- * in the order given below. An observer may register separately for each phase
- * of the process depending on its needs. The subject passed to the observer's
- * Observe() method can be QI'd to an nsIProfileChangeStatus.
- *
- * "profile-approve-change"
- * Called before a profile change is attempted. Typically,
- * the application level observer will ask the user if
- * he/she wants to stop all network activity, close all open
- * windows, etc. If the user says NO, the observer should
- * call the subject's vetoChange(). If any observer does
- * this, the profile will not be changed.
- *
- * "profile-change-teardown"
- * All async activity must be stopped in this phase. Typically,
- * the application level observer will close all open windows.
- * This is the last phase in which the subject's vetoChange()
- * method may still be called.
- * The next notification will be either
- * profile-change-teardown-veto or profile-before-change.
- *
- * "profile-change-teardown-veto"
- * This notification will only be sent, if the profile change
- * was vetoed during the profile-change-teardown phase.
- * This allows components to bring back required resources,
- * that were tore down on profile-change-teardown.
- *
- * "profile-before-change"
- * Called before the profile has changed. Use this notification
- * to prepare for the profile going away. If a component is
- * holding any state which needs to be flushed to a profile-relative
- * location, it should be done here.
- *
- * "profile-do-change"
- * Called after the profile has changed. Do the work to
- * respond to having a new profile. Any change which
- * affects others must be done in this phase.
- *
- * "profile-after-change"
- * Called after the profile has changed. Use this notification
- * to make changes that are dependent on what some other listener
- * did during its profile-do-change. For example, to respond to
- * new preferences.
- *
- * "profile-initial-state"
- * Called after all phases of a change have completed. Typically
- * in this phase, an application level observer will open a new window.
- *
- * Contexts for profile changes. These are passed as the someData param to the
- * observer's Observe() method.
- * "startup"
- * Going from no profile to a profile.
- *
- * The following topics happen in this context:
- * profile-do-change
- * profile-after-change
- *
- * "shutdown-persist"
- * The user is logging out and whatever data the observer stores
- * for the current profile should be released from memory and
- * saved to disk.
- *
- * "shutdown-cleanse"
- * The user is logging out and whatever data the observer stores
- * for the current profile should be released from memory and
- * deleted from disk.
- *
- * The following topics happen in both shutdown contexts:
- * profile-approve-change
- * profile-change-teardown
- * profile-before-change
- *
- * "switch"
- * Going from one profile to another.
- *
- * All of the above topics happen in a profile switch.
