That is what the mozilla documentation suggests @ https://developer.mozilla.org/en/IndexedDB/Using_IndexedDB https://developer.mozilla.org/en/IndexedDB/Using_IndexedDB "Obviously, browsers do not want to allow some advertising network or malicious website to pollute your computer, so browsers prompt the user the first time any given web app attempts to open an IndexedDB storage. The user can choose to allow or deny access. Also, IndexedDB is completely disabled in the privacy modes of browsers (Private Browsing mode for Firefox and Incognito mode for Chrome). The whole point of private browsing is to leave no footprints, so attempting to open a database fails while in this mode." Testing it in chrome it looks like it is working fine, I should know better than to trust the docs :)
