I've read this question: Chrome Extensions & Javasctipy Database but I want an answer with more details and more clear.

How can I store some of my extension settings?

Is it possible to use a database to do such things with JavaScript?

Is there any good tutorial on it?

I don't want to use Local Storage, because I do not want the behavior of SESSIONS

Thanks.

You could use chrome.storage.sync or chrome.storage.local (docs). Both are local storage (not session storage); sync has the additional advantage that it syncs to the user's Google account if they've connected Chrome to it.

The following page lists the storage mechanisms in HTML5. WebSQL gives you a pretty good database for your javascript to use.

UPDATE: It has been some time since I posted this. WebSQL has been dropped. Browsers will probably still continue to support it, but all the implementations have been SQLite. IndexedDB is the way to go now. I have used it and it is a little hard to get into, but works well for a client side database.

UPDATE AGAIN: Chrome changing things. See T.J. Crowder's Answer.

I believe this is a simple solution for you if you just want to save some settings. It also has some examples, hope it helps.
