Here's some very interesting information about that:

(see 5. Client Configuration)

It's configurable. By default the 1.5 version (windows at least) checks the list 
of trusted issuers and tries to send one that matches without a user prompt. So 
the default of firefox 1.5 has been chosen pretty good, lucky us... (don't know 
what happens if there are multiple certs that match)

note that IE is a party crasher when you set the http connector to 
clientAuth="want" as that will popup the (empty) list for all users not having a 
cert, which is most likely the largest group at the moment. That option is also 
configurable though:
"Don't prompt for client certificate selection when no certificates or only one 
certificate exists"
It's disabled by default. I wonder why MS didn't put that at enabled by default, 
ah well...
