No persistent data on Firefox OS using ember-localforage-adapter

I've got an issue with using this adapter. I'm a noob in Ember, so it might be (and probably is) my error...

Ember 1.13.8 Ember Localforage Adapter 1.13.1

• Adding an entry is fine - adapter is called.
• Adapter isn't called when the application is started.
• Data is missing when an app is reloaded.
