In Firefox the password are not cleaned, even if this option is selected. Only saved forms are cleaned, not the password list.
Moreover the cleaning option in Chrome does not clear the passwords if not selected...There are two separated options for forms and passwords.
When using CCleaner with "Saved Form Information" option ticked under Google Chrome, the password list is totally cleaned.
Please fix it.
(using ccleaner 2.30 and chrome 4 stable)
