SeaMonkey comes with the the look and feel familiar to users of its predecessors, the Mozilla Application Suite and Netscape Communicator packages, but adds many new features as well as back-end changes that improve security, stability and performance. Some highlights are: drag&drop reordering of tabs, phishing e-mail detection, support for a single shared inbox when using multiple accounts, and support for Scalable Vector Graphics (SVG).
The SeaMonkey project is a community-based project hosted at mozilla.org that emerged around Mozilla’s suite codebase when the Mozilla Foundation announced it would discontinue further development of its suite product. The new project is dedicated to keeping this suite alive and developing it into an even more modern and complete internet software package.
