I was reading the [Mozilla Doc](https://developer.mozilla.org/en/Storage) about Firefox Addon Storage and it says:

**Storage is a SQLite database API. It is available to trusted callers, meaning extensions and Firefox components only.**

Well, it says its available to firefox only, but I managed to acess my Echofon storage by using a simple SQLite Manager for Linux. I found the .sqlite at: 

/home/user/.mozilla/firefox/pmk9mj59.default/twitterfox\_1.9.sqlite

The question is: how to protect my .sqlite storage in order to have it safe from external resources.
