You can try to edit the trust flags of that see (remove all trust) and 
when encountering a site with a certificate from that CA to add an 
exception. Wild cards go as well with the exceptions.

No, so far there aren't any yet.

LOL!!

I AM THE REPRESENTATIVE AND FOUNDER OF STARTCOM! I run the StartCom CA 
(the one located in Israel) and I can assure you that there is no such a 
thing, never was and never will be! :-)

More on this topic: I guess the Mossad doesn't need the services of 
StartCom nor does any "party of interest" use certificates issued by a 
legitimate CA either. That's just pure FUD.

Nothing would happen...but I'll let the representative of Verisign 
confirm that by himself perhaps...
