SeaMonkey screenshotSeaMonkey is a comprehensive software suite that will meet all your Internet related needs while you are surfing the web. The application was promoted by Netscape and Mozilla platforms, allowing the SeaMonkey team to constantly develop the project for providing high-quality updates to this concept. The software suite packs an IRC chat, email & newsgroup client featuring an included RSS reader, HTML editor, Internet browser, and various web development tools.

SeaMonkey is actually the heir of the popular Netscape Communicator and continues in that direction providing a modern, cross-platform architecture based on the Mozilla project. The browser provided by Seamonkey is based on the same reliable rendering engine and application platform as Mozilla Firefox, offering popular and efficient functions like feed detection, find as you type, tabbed browsing, popup blocking, smart location bar, and increased functionality for a great web experience.

SeaMonkey's Mail and Newsgroups client has many things in common with Mozilla Thunderbird and provides tags and mail views, tabbed messaging, address books with LDAP support, adaptive Junk mail filtering, web feeds reading, multiple accounts, S/MIME, and many more.

There is also a set of additional utilities that includes the ChatZilla IRC chat application, an easy-to-use HTML Editor, a JavaScript debugger, a DOM Inspector and other powerful web tools.

You may extend SeaMonkey's functionality by using various plug-ins and add-ons.


  • Internet suite with browsing, email and chat capabilities.
