Obsolete since Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

This interface represents an event that occurs to notify interested parties about changes to the contents of a DOM storage space; it is used for both session storage and local storage.
Gecko 1.8
Gecko 2.0
Inherits from: nsIDOMEvent Last changed in Gecko 1.8 (Firefox 1.5 / Thunderbird 1.5 / SeaMonkey 1.0)

When a DOM storage event is received, the recipient can check its domain attribute to determine which domain's data store has changed. If the value of the domain attribute is "#session", then the session storage has changed.

Note: This interface describes the old, non-standard form of this event. You should use the nsIDOMStorageEvent interface instead.
