SeaMonkey is a free and open source web browser produced by Mozilla. It has a GPL license and is designed to work on many operating systems, and is the continuation of the Mozilla suite.
SeaMonkey consists of a web browser "SeaMonkey Navigator", which is a descendant of the Netscape family, an e-mail and news client program "SeaMonkey Mail & Newsgroups", which shares code with Mozilla Thunderbird, an HTML editor "SeaMonkey Composer" and an IRC client ChatZilla. The software suite supports skins. It comes with two skins in the default installation, Modern and Classic.
