So you're saying that there are actually two files stored by the browser ? One of them is completely secure and uncrackable, and the other is the bookmark file that contains everything except the site passwords? This secure file naturally requires that you type in a 20-odd random character password to start your browser? And exists independently of the operating system and whatever spyware is installed on your computer?

Not being a Mozilla user I haven't bothered to look at its security model, but my objection is based entirely on the reluctance of users to safeguard their machines. Anything that makes it easier to access their bank account via information stored on their computer is going to increase vulnerability. Banks generally take the easy way out and say "if if came from your computer it's from you" (like so many other companies do), and this just exacerbates that. Writing the password on a note taped to your monitor is more secure, dammit.

(I used to get periodic hassles from idjits telling me to change the default email address in my program, because obviously moz can only ever refer to a browser... why the word existed before the browser is a mystery)
