Firefox-3 Passwords Information
Due to security restrictions in the Firefox browser, the scripts used to display your password information can't be run from a website. You must save that page to local disk and open it from within Firefox to allow the scripts to do their work.
Once you have that page saved, use File > Open File... to open the page and see your password information.
NoScript extension users must allow file:// to run.
