This article deals with Firefox or Mozilla Suite not remembering user names and passwords you enter. If Firefox remembers the password after you enter a user name, see Password only filled after entering user name.

Password Manager settings

You must have the "Remember passwords" feature enabled for the browser to remember them. In Firefox 2, make sure Tools -> Options -> Security / Passwords -> "Remember passwords for sites" is checked.

Additionally, you may have once told the browser to never save the passwords for the site. In Firefox 2, check the list under Tools -> Options -> Security / Passwords -> Exceptions.

Passwords cleared with Clear Private Data

Firefox's Clear Private Data feature may be set to clear your passwords when you close Firefox. Make sure that Tools -> Options -> Privacy -> "Always clear my private data when I close Firefox" is unchecked, or that under Settings, "Saved Passwords" is not checked.

Passwords not used in Firefox 2.0.0.2 or 1.5.0.10

A fix for a security problem had the unintended side effect of not filling in the password if you have multiple passwords saved for that site. This bug was fixed in Firefox 2.0.0.3 and 1.5.0.11 - upgrade your browser to these versions or higher.[1]

Sites prohibit password saving

Some websites, for example Hotmail, Yahoo! Mail, and some banks, specify that your username and password should not be saved. You can override this behaviour.

Using a bookmarklet

1. Bookmark the "remember passwords" link on this page.
2. Go to the log in page of the site you want to save your details.
3. Enter your login and password, but do not submit.
4. Open the bookmark you just made. (Nothing will appear to happen).
5. Submit.

On subsequent visits, your user name and password should be filled in.
