Sounds as though you need to remove the old password, then return to the site and log in and save it again. But I don't use this feature, so I'm just guessing.

Sorry, that does not work either.

If you enter a new password Firefox should offer to change the password. *You may not need to delete the old password. Try "Refreshing" the page, entering the site again, you may need to let Firefox fill in the old password, then enter the new password, and Firefox should ask to save the new password. See: **http://kb.mozillazine.org/Deleting_autocomplete_entries *If you delete the old password, you may need to "Refresh" the site after deleting the old password. If you want to delete the password that has been saved do the following: #In the Tools menu select Options to open the options window #Go to the Security panel #Click the "Saved Passwords" button to open the passwords manager #Select the site in the list, then click Remove <br /> -------------------------- <br /> '''You need to update the following.'''
