StorageEvent Interface
nsIDOMEvent
Last changed in Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)
A StorageEvent is sent to a window when a storage area changes.
Although this event existed prior to Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)
, it did not match the specification. The old event format is now represented by the nsIDOMStorageEventObsolete
interface.
