Title: Ignore window.globalStorage in Ember#identifyNamespaces when it's old Firefox storage object

As noted in https://github.com/emberjs/ember.js/issues/341, trying to read 'isNamespace'-property from ```window.globalStorage``` will cause security exception in older Firefoxes.

This patch tries to skip this troublesome property when we can be quite sure that it's the Firefox-version of the property.
