hello, websites can specify if browsers should be able to save username/passwords (through the autocomplete="off" attribute in the login form in the html source code) - this is often the case when a higher level of security is presumably required by those sites. you can either [https://addons.mozilla.org/firefox/addon/remember-passwords/ install an addon] or [https://www.squarefree.com/bookmarklets/forms.html use a bookmarklet] to circumvent this restriction. [[Usernames and passwords are not saved]]
