Firebird exists, and continues to be improved, thanks to a community of volunteers who donate their time and skills to bring you this wonderful piece of software. But volunteer work alone is not enough to keep an enterprise-level RDBMS such as Firebird up-to-date. The Firebird Foundation supports Firebird development financially by issuing grants to designers and developers. If Firebird is useful to you and you'd like to give something back, please visit the Foundation's pages and consider making a donation or becoming a member or sponsor.
