When you look at the top five web browsers on today's Internet, which are undoubtedly Firefox, Internet Explorer, Google Chrome, Opera and Safari you will notice that all but one reduce their functionality to Internet browsing. Opera is the only browser of the five that offers an integrated email client.

The idea behind SeaMonkey is to provide users with an all-in-one Internet application for their needs. SeaMonkey is based on the Mozilla platform which is also used by the Firefox web browser. Unlike Firefox it includes additional tools and Internet applications like an email client, IRC chat client or news feed client. It shares code with both Firefox and Mozilla Thunderbird.

Experienced Firefox users may weight in that they can install add-ons that add the functionality to the browser. While that's true for some features like the IRC chat, it is not true for others like the email client. When you look closer, you will notice that SeaMonkey has integrated some of those add-ons in the browser.

Users basically get Firefox plus already installed add-ons and additional integrated tools like the email client. That's handy for Internet users who are not tech savvy enough to install add-ons for instance, or users who want one software for all their Internet needs. SeaMonkey offers to import data from Thunderbird if the email client is discovered during installation which is handy for users who want to make the switch.

The release notes list the new features of SeaMonkey 2.1, among them integration of data synchronization, the Firefox add-on Personas which can be used to modify the browser's theme more easily, a new data manager for managing permissions, cookies, passwords and form data, and improved plugin handling.

The release benefits from Mozilla core platform changes, resulting in better startup and shutdown performance, better memory management, better HTML5 support and protection from out of date plugins.

Windows 7 users benefit from jump list and download progress support and Linux users from desktop notifications.

Interested users can download SeaMonkey 2.1 from the official project website. The Internet software is available for Windows, Linux and Mac, and is offered as a localized version.

As a note on the side. SeaMonkey 2.1 is still using the old Firefox design, making it an excellent alternative for users who do not want to make the switch to Firefox 4 because of the design.

    I’ve tried to set up my email in the Sea Monkey, and am having no luck. It is a yahoo account, and I found some directions through a search engine, but it’s not working – – darn!

    opera is more of an all internet suite than seamonkey, it has web server capability, email, irc and more. ;P

    After sliding sideways into Linux with a pre-installed Xandros laptop in 2004 I used SeaMonkey for years. If I hadn’t turned into such a complete Opera fanboy since then I’d probably still be using it now.

    This article is about SM not Opera but Martin did not mention that Opera is in fact a (more or less) complete Internet Suite that includes all functions SM has and more.

    Don’t forget that seamonkey’s design is originally based on the old netscape communicator browser
