Firefox browser doesn't ask that when you open the Browser itself. You need to check your password/login settings to see if they are saving the logins correctly. I have my Firefox remember my logins and just have to click to confirm the right login without having to type unless I update my passwords for saved sites. https://support.mozilla.org/en-US/kb/logins-sync-autofill-saving-firefox-preview#:~:text=Enable%2Fdisable%20saved%20passwords,-Tap%20the%20menu&text=Tap%20Settings.,logins%20and%20passwordsSave%20passwords. https://support.mozilla.org/en-US/kb/autofill-logins-firefox https://support.mozilla.org/en-US/kb/password-manager-remember-delete-edit-logins
