This is because you already "accepted" a test certificate from a 
different computer and FireFox is complaning that it's not unique.  You 
need to purchase a valid cert from a certificate authority (Verisign, 
Thawte...).

If you want SSL for pure encryption and don't care to pay for a valid 
cert, then you can just generate one.

You can also just go to FireFox preferences and delete the offending cert.
