firestarter start failure?

[Robert Holtzman]

Just had occasion to reboot 8.04 and got a boot message that firestarter 
had failed to start. When the boot was complete I opened firestarter and 
it's status was shown as active.

ps -aux showed:

holtzm    7005  0.8  0.6  33268 12612 ?        S    21:54   0:00 gksu 
/usr/sbin/firestarter
root      7006  0.7  0.7  46048 15364 ?        Ssl  21:54   0:00 
/usr/sbin/firestarter

I didn't understand the explanation in the ps man page of the STAT column 
codes (S and Ssl).

Anyone want to give me some pointers?

TIA
