SeaMonkey 1.1.4

SeaMonkey is a web-browser, advanced e-mail and newsgroup client, IRC chat client, and HTML editing made simple -- all your Internet needs in one application. The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as Mozilla Application Suite . Whereas the main focus of the Mozilla Foundation is on Mozilla Firefox and Mozilla Thunderbird, our group of dedicated volunteers works to ensure that you can have everything but the kitchen sink and have it stable enough for corporate use.

The Internet browser at the core of the SeaMonkey suite uses the same rendering engine as its sibling Mozilla Firefox, with popular features like tabbed browsing, popup blocking, find as you type and a lot of other functionality for a smooth web experience.
SeaMonkeys Mail and Newsgroups client shares lots of code with Mozilla Thunderbird and features adaptive Junk mail filtering, labels and mail views, multiple accounts, S/MIME, address books with LDAP support and is ready for both private and corporate use.
Additional components include an easy-to-use HTML Editor, the ChatZilla IRC chat application and web development tools like a DOM Inspector and a JavaScript debugger.
If that is still not enough, SeaMonkey can be extended with numerous Add-Ons that provide additional functionality and customization for a complete Internet experience.
