Try closing Firefox and when you come back don't let it log you in automatically, or if it does log back out. Then when you come to the main page of the forum, click Inbox at the bottom and log in from there and allow it to save your password. I know that Firefox has asked me to save my forum password and also a password from the Private mail page. That might fix the problem.
