Tenta colocar isso no arquivo:

<property name="hibernate.dialect">org.hibernate.dialect.FirebirdDialect</property>

entao este é meu arquivo persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"

tenta trocar hibernate.connection.dialect por hibernate.dialect

<property name="hibernate.dialect">org.hibernate.dialect.FirebirdDialect</property>
