No, you do not have to distribute your source code just because you link
your application to Firebird libraries. You also do not need to
distribute Firebird source code to anyone.

The Firebird license is more flexible than GPL and allows you to make
use of Firebird in commercial and non-commercial situations without any
such requirements.
