How to access simple-storage from WebExtensions code?
Context: our extension (Ghostery) is posted in Mozilla store, and is SDK-based. Currently we’ve ported code to WebExtensions API. We plan to upgrade our users once Firefox 49 is out. The problem is the transfer of user settings during upgrade. In the SDK based app user settings are saved in simple-storage. We need a read-only access to it from a WebExtensions based code.
