What is "seamonkey"

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 standalone projects such as 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 far more traditional-looking interface of Netscape and the Mozilla Suite. Many Firefox and Thunderbird add-ons can be converted to make them compatible with SeaMonkey if they aren't already.
