You can make Firefox fill in login information for a different account each time you visit. If you have more than one account for a site, Firefox can save all your logins.
Select the Create New Login button at the bottom left side of the Firefox Lockwise page to manually add a website address, login, and password. Click the Menu button and select Logins and Passwords. You can also manually add website logins.
The Firefox Password Manager securely stores the usernames and passwords you use to access websites and then automatically fills them in for you the next time you visit a website. When you enter a username and password that you haven’t already saved for a website, Firefox will ask if you want to save it.
