This sounds an awful lot like http://bugzilla.mozilla.org/show_bug.cgi?id=3D70213 which should have been fixed for 1.6. Firebird 0.7 was based on 1.6a where this fixed first showed up, so perhaps they've regressed. You might try reopening this bug with your new data. In the meantime, if you're not using IPv6, try either removing INET6 from your kernel, or setting net.inet6.ip6.auto_linklocal to 0 in /etc/sysctl.conf and rebooting.
