SeaMonkey is a free and open-source Internet suite. It is the continuation of the former Mozilla Application Suite, based on the same source code, which itself grew out of Netscape Communicator and formed the base of Netscape 6 and Netscape 7.
SeaMonkey was created in 2005 after the Mozilla Foundation decided to focus on the standalone projects Firefox and Thunderbird. The development of SeaMonkey is community-driven, in contrast to the Mozilla Application Suite, which until its last released version (1.7.13) was governed by the Mozilla Foundation. The new project-leading group is called the SeaMonkey Council.
Compared to Firefox, the SeaMonkey web browser keeps the more traditional-looking interface of Netscape and the Mozilla Application Suite. It also retains the legacy XPCOM-based add-on system which allows the user to extend SeaMonkey by modifying add-ons for Thunderbird or the add-ons that were formerly compatible with Firefox before the latter switched to WebExtensions.
