Hm, this code can't be what you're actually using; I see multiple bugs but none of them would result in the error message you posted...

I'm new to indexed db and at first I wasn't surprised that this simple example didn't work for me. Initially I thought that the issue should be in code however the code works on Chrome. So I think the issue should be in browser. Am I the only one who have experienced this?

I would recommend reading https://developer.mozilla.org/en/docs/IndexedDB/Using_IndexedDB if you're new to indexedDB.

The most obvious problem with your sample code is that you don't wait for the success event from the open request before continuing your work (i.e., you need to wait for |request.onsuccess| to be called). The next big thing is that there is no |request.onupgradeneeded| handler, so you never have the opportunity to create an objectStore (creating and removing objectStores is only allowed during a upgradeneeded event).

Hope those pointers help!

Thanks a lot for help! The error wasn't on fly resolved by this and there started to happen very funny things in code execution. The issue was solved by simple machine reboot. I previously tried several FF reboots however it seems that it wasn't enough.

The info in https://developer.mozilla.org/en/docs/IndexedDB/Using_IndexedDB is great and I haven't found anything even similar to that quality.

(Sounds like the test case here had some bugs that once addressed indicate there's no problem in the IDB impl.)
