Many websites use both a user name/password and a 'secret question' for sign in. The second part usually involves entering the answer to a randomised question, like 'mother's maiden name'; 'place of birth' etc. Whenever this happens, Firefox asks if I want to update the password it stores. Obviously I don't because it will be changing my actual password, and the answer will be different the next time anyway. This happens on every sign in and there's no way I can see to tell Firefox not to; the only options are to update or 'not now' I still want Firefox to remember the main user name and actual password, so how do I prevent it from asking about these pseudo passwords without disabling its recording of the main login details?
