I've had a much easier time getting firefox to do SPNEGO than IE9.
If you are using an external kerberos (MIT or heimdal) you will need to 
tell firefox to disable sspi (in about:config).  Both IE and firefox need 
to be told which sites they are permitted to use negotiate auth against, 
though -- firefox has a negotiate.trusted-uris entry in about:config, and 
IIRC IE needs hostnames configured to be in the local intranet zone.

In my own testing, I was only ever able to get IE9 to do SPNEGO if I 
explicitly inserted the correct service ticket into the MSLSA cache 
manually, or if the machine was joined to an AD domain.
