From what I can grasp here: https://developer.mozilla.org/en-US/Firefox/Releases/30/Site_Compatibility#Security If a field or form has autocomplete="off" set, the password manager should prompt the user to save the password, but the password can not be auto-filled into the field. This is not what I'm experiencing. I have a simple form with email and password field. Both the form itself and the fields have autocomplete="off", but Firefox 30 will still let me store the details and auto-fill them. I cannot allow this, as it breaks Angular JS's binding causing things to not work.
