Cookie usage page displays on contact form submit

I have a user who is using firefox on pc. When he submits the contact form, the cookie usage page displays.

He has firefox set to accept cookies and 3rd party cookies but still the same error.

He has this problem with verison 1.3.9f but not version 1.3.8b.

Any ideas ?

Thanks in advance

I still haven't found an answer to this. The funny thing is, I can't duplicate the error on my machine to test for possible solutions. I have told the web browser to block all cookies and set the security level to high and I cant seem to make the cookie page come up at all from my computer.

Does anyone have some direction on this ?

Thanks
