Wonder whatever happened to the Netscape Communicator suite, and wish you could use it again with a modern engine? You can. It’s called SeaMonkey.


SeaMonkey is more than just a browser. It also has a full email client, an IRC client (ChatZilla) and web page editor (Composer). It’s also compatible with some Firefox add-ons, so it is extensible.

What do you need to run SeaMonkey?

Not much in the way of computer power. The system requirements only call for Pentium 233MHz CPU with 128MB RAM and 50MB free HDD space. In Windows the minimum supported OS version is 2000. On the Mac the oldest OS supported is 10.4 Tiger. In Linux there are six libraries required, which most Linux users would already have (the minimum Ubuntu that has it all is 6.10 Edgy).

What does SeaMonkey look like?

The browser by default keeps things on the simple side.


No fuss, no muss, and if you’re a Firefox user you’ll find some familiar bits here and there.

Can you run Firefox and SeaMonkey at the same time?

Yes, they do run independently of each other – mostly. In the Windows OS you may on rare occasion find some things (mainly extensions) that Firefox and SeaMonkey "share", but it’s nothing that interrupts normal operation.

Where are the add-ons/extensions?


I do recommend sorting through them in a very specific way.

When you click that link, click Advanced on the right (under the big green arrow), set the Application to Seamonkey and version to 2.0, like this:


If you want to search all add-ons at this point, just hit the big green arrow at right.

The reason you want to do this is because several 1.x add-ons do not work in 2.x versions of SeaMonkey, so you might as well only view the ones that are known to work properly.

Again, if you’re a Firefox user, you will see many add-ons listed that are also available for Firefox. You may even find several that you use in Firefox already.

Who would like SeaMonkey?

I’d say this would be a good browser to have installed on a secondary computer (or a server) for those that want everything "contained", so to speak. Being that SeaMonkey is a suite, it can act as an all-in-one. For example, you can use the browser for normal browsing purposes, have an IMAP-enabled email account (such as Gmail) in the mail client and use ChatZilla for your IRC.

Also, being this is multi-platform, you get the same experience on Windows, Mac or Linux, so that’s a plus.

Lastly, yes it does support the current version of Flash with no issues.

Have you used SeaMonkey lately? Did you find it a good browser?
