Firefox allows you to securely store usernames and passwords for websites in its Password Manager. When you visit one of the websites again, Firefox automatically fills in the username and password to log you in.
If you need to find out what your password is for a specific website for which you saved your logon information, you can easily do so. To view your saved passwords in Firefox, select Options from the Firefox menu.
NOTE: You can open the Options dialog box by selecting Options on the main Firefox menu or on the submenu.
On the Options dialog box, click the Security button at the top. In the Passwords box, click Saved Passwords.
The Saved Passwords dialog box displays each site for which you have saved your username and password, and displays the usernames. The passwords are hidden by default. To view the passwords, click Show Passwords.
A confirmation dialog box displays to be sure you want to show your passwords. Click Yes if you still want to view your passwords.
A Password column displays and all your passwords are shown. It’s a good idea to make sure no one is lurking about near you because the passwords display in plain text on the dialog box.
To delete a password from the Password Manager, select the appropriate site and click Remove. To delete all your passwords, click Remove All. To hide your passwords again, click Hide Passwords.
NOTE: You can search for a specific site using the Search box. As you type the search term, the results display in the list box. To clear your search and list all the sites, click the X button.
If you’re going to use the Firefox Password Manager, we highly recommend that you apply a master password to your stored usernames and passwords. Without a master password, if someone gains access to your account, they can easily open the Password Manager and view your passwords. To add a master password, open the Options dialog box again and select the Use a master password check box.
The Change Master Password dialog box opens. Enter a master password in the Enter new password edit box and again in the Re-enter password edit box. Click OK.
Click OK to close the message telling you that your master password has been successfully changed.
If you want to change your master password in the future, click Change Master Password on the Security screen on the Options dialog box. To close the Options dialog box and save your changes, click OK.
Now, when you click Saved Passwords on the Options dialog box to view your passwords, you must enter your master password first.
Some websites do not allow the saving of usernames and passwords, therefore, the Firefox Password Manager will not work with those sites. Also, some websites provide a option, in the form of a check box, that allows you to stay logged in on that website. This is an independent function of the website and works whether or not you have saved your login information for that website in Firefox.
