No security exception for SSL EV certificates in Fire Fox 3.6.17

May 18, 2011 at 10:05 am (Technology) (, )

Today I learned something new about Fire Fox 3.6.17. I was migrating a SSL EV certificate from a IIS server onto a Virtual Server that is located on a KEMP LoadMaster. This test server on the LM is running a prototype/test site. Therefore, the domain name doesn’t match the domain name that the SSL cert was created for. This normally will create a SSL name mismatch error in the web browser. This error normally can then be bypassed by the user, this process is called “Security Exception” in Fire Fox. I went to add this exception and found that Fire Fox wouldn’t allow me to add it. What’s interesting is that the exception window tells you that the identification of the certificate is so positive that there is no reason for you to add an exception.

This site provides valid, verified identification. There is no need to add an exception.

I think this is a good thing.  It really helps make the EV certificates more strong and adds value to them.  I guess I’ll go back to using a self signed certificate for testing.

No security exception.
