Where does Firefox store saved passwords?

Question

I'm going to create a plugin to a face recognition system for Firefox's saved passwords as my final year project, but yet i haven't any idea about how saved passwords are implemented in Firefox. if anybody know about that, Please help me.

Where does Firefox store saved passwords? How does it choose appropriate password when entering username?

Answer 1

You can find your saved passwords by going to:

Firefox --> Options --> Security

and click Saved Passwords. Your passwords are ordered by site. You'll get a list of all usernames, and you have to click Show Passwords to actually be able to see your passwords. I suggest using a master password (you can set this in the security tab) so no one else can access your passwords.
