How to Use Autofill When Signing Into Yahoo on Firefox

by Kevin Lee

When you enable Firefox's autofill function, the browser populates form fields with values it remembered when you filled out the form the first time. This feature comes in handy if you log in to Yahoo frequently because you don't have to type a username or password to sign into your account. Firefox can also remember multiple usernames and passwords if you have more than one Yahoo account. Before you enable this feature, consider one important privacy fact; if you walk away from your computer, anyone can log into your Yahoo account without knowing your username or password.

Click Firefox's "Tools" menu and select "Options." If you don't see the Tools menu, click the "Firefox" button and then click "Options." The Options window opens.

Click "Privacy" and then click "Remember History." Click "OK" and visit a Yahoo page that requires you to log in.

Enter your username and password in the appropriate text boxes and click "Sign In." A pop-up asks if you would like Firefox to remember the password for your account. Click "Remember Password" to close that pop-up. Firefox will remember your login information.


  • The next time you visit Yahoo, click inside the "Yahoo! ID" text box and select the username that appears in a drop-down menu. Firefox fills in the password automatically. You can then click "Sign In" to log in to your account.
  • Every time you sign in to Yahoo using a different username, Firefox asks if you'd like it to remember the login information. If you click "Remember Password," it adds the username to the drop-down list. When you visit Yahoo later, you can click the "Yahoo! ID" text box to view all the usernames you've allowed Firefox to remember. Click the one you'd like to use and then click "Sign In" to sign in using that username.
