SeaMonkey is an open-source web browser and Internet suite. It is the continuation of the former Mozilla Application Suite, based on the same source code, which itself was based on Netscape Communicator. The development of SeaMonkey is community-driven. The SeaMonkey web browser (Navigator) has a far more traditional looking interface than the Mozilla Firefox browser and is aimed more at advanced users, web developers and corporate users.
SeaMonkey uses much of the same Mozilla source code used by Firefox.
