SeaMonkey

SeaMonkey is the all-in-one internet application suite formerly known as the Mozilla Application Suite, containing a web browser, email and newsgroup client, HTML editor, and chat client. SeaMonkey is built on the same code as the Mozilla Firefox web browser and Thunderbird email client, and shares the same branding and trademarks. It is produced by the SeaMonkey Project, a community-driven open-source project whose goal is to collaborate on developing a modern, standards-compliant web browser.
