I'd say the one in /etc is meant to be used for the admin to make
edits to and for programs to read, while the other one might just
be a pristine backup copy reflecting the default state of the file.

The FHS doesn't exactly support this interpretation, though.

For a definitive answer, do an strace to run the program in question,
redirect the output and grep for "firebird.conf". Of course, that's
only the status quo, not the intent; but let's assume status quo and
intent are congruent.
