Changes

Users can enable a "master password" in their browser, which securely encrypts all their stored passwords. The current implementation can be awkward to use and has some limitations, see [https://bugzilla.mozilla.org/show_bug.cgi?id=322617 bug 322617]. Fixing this would involve having password manager being more involved with the cryptography operations -- deriving a key from a passphrase with PKCS#5, and using NSS and PKCS#11 to encrypt/decrypt entries.

Firefox 3 will support offline abilities, such that web developers can write their apps so they work even when no network is present. Good headway has been made already [http://www.bluishcoder.co.nz/2007/02/offline-zimbra-with-firefox.html porting Zimbra]. Pick another web app and add offline support, for example: [http://moodle.org Moodle].
