Hello, For autofill logins, do this : Go to Settings -> Privacy & Security -> Logins and Passwords and check "Autofill logins and passwords". Next, to make sure it remembers to not do 2FA every time, do this : Settings -> Privacy & Security -> Cookies and Site Data and make sure "Delete cookies and site data when Firefox is closed" is unchecked. Also, when logging into a webiste, if they offer so, check the box that says "remember this device/login", where this makes sure you don't have to do 2FA every time.
