Back in the 90’s, Internet Service Providers used to supply ‘all-in-one’ suites so that you had everything you needed to connect to the Internet. Indeed, Turnpike made a fortune selling their suite to Demon, when it was primarily made up from third-party applications (Mozilla, Eudora etc).
These all-in-one integrated Internet suites were designed to work with the Internet provider. It would be all pre-configured so that you install, select your local POP (a POP was a local phone number for dialup users), entered your supplied user name and password, and you’d find that you’d have a web browser, email client, chat application and dialup manager.
Mozilla SeaMonkey is an all-in-one Internet suite from the same guys that gave use Firefox and Thunderbird. Indeed, it contains the latest Firefox and Thunderbird, along with an IRC chat application and also Mozilla’s HTML editor for creating your own web pages.
The latest v2 has been rebuilt on top of the modern Mozilla platform that also powers Firefox and improved with additional features, resulting in world-class add-on management, feed support, modern look, session restore, tabbed mail, smart location bar, HTML5 features, and more.
Note that this is the portable version of SeaMonkey.
