Adjusting the levels of logging to your console though will affect all 
programs, so bear in mind if you raise the filtering level to cut out 
more logging, it will cut out logging from all applications.

Even though I don't know how you would adjust Firestarter, it should 
have config options to control its logging for itself.

Just looking into firewalls myself, that's why I chipped in.
