Try using this script to launch Firebird

Change the FBDIR= line to the path to where you've installed Firebird, then, instead of running Firebird, run this script. Save it somewhere convenient (/home/jaan/bin ?) and change it's permissions so you can execute it. I hope it works as well for you as it works for me.
