I run JJ 9.04 on my desktop and every time I login, after reboot or
logout, I must start Firestarter (firewall interface).  Sometimes that
is all it takes and I am online, other times, I have to click on 'Stop
Firewall', wait, then click on 'Start Firewall'.   At this juncture I
have no idea why, but it works for me.  I also have a Dell linux
notebook with 9.04-KDE 4.2.2 and it does not do that.  Go figure!
Good luck!
