/**
  * Storage is a SQLite database API. It is available to trusted callers, meaning extensions and Firefox components only.
The API is currently "unfrozen", which means it is subject to change at any time; in fact, it has changed somewhat with each release of Firefox since it was introduced, and will likely continue to do so for a while.
Note: Storage is not the same as the DOM:Storage feature which can be used by web pages to store persistent data or the Session store API (an XPCOM storage utility for use by extensions).
