When rummaging through `window`-attributes, Ember#identifyNamespaces causes a security exception to be thrown in Firefox 3.6 (but not in 8).
It seems to stem from trying to read value from window.globalStorage like this:

```javascript
var ret = obj[META_KEY];
```
which (based on https://developer.mozilla.org/en/DOM/Storage#globalStorage) tries to read the globalStorage for host `META_KEY`.

Curiously, calling `window.globalStorage["foo"]` causes security exception to be thrown in both the old and new Firefox.
