The SeaMonkey Council is proud to announce SeaMonkey 1.0, the first end-user release of their internet suite. SeaMonkey is available as a free download from its mozilla.org-hosted website, features a state-of-the-art web browser, a powerful email client, a WYSIWYG web page composer and a feature-rich IRC chat client. For web developers, mozilla.org’s DOM inspector and JavaScript debugger tools are included as well.
This seems to have come a long way since I used SeaMonkey 0.1! Definitely check it out here if you want to check out an all-in-one suite.
