Is there a way to enable window.localStorage inside documents living in a XUL <iframe> or <browser> in a xulrunner-based app (not FF)? This is the result for the time being:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE)
 [nsIDOMStorageWindow.localStorage]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"]

I am asking because BespinEmbedded 0.7.1 relies on it. Without that, impossible to embed Bespin 0.7.1 inside a xulrunner-based app... :-(
