Want your browser, email and newsgroups on a USB stick you can use on any PC? SeaMonkey Portable keeps them in one package. It combines web browsing, email, newsgroups, and page-editing tools, and can run from removable storage, local storage, or cloud storage without a standard installation.
SeaMonkey brings browsing and communication together
The browser sits alongside an email and newsgroup client, so web pages and messages are available within the same application. A built-in feed reader adds a place to follow web feeds alongside those activities.
The portable package can be run from a removable drive, local storage, or cloud storage without installing SeaMonkey as a conventional Windows application.
The mail client handles email and newsgroups
Use the integrated client to read and send email or follow newsgroups.
The feed reader is another part of the suite: it provides a dedicated way to keep up with feeds without treating every update as an ordinary email message.
The HTML editor and development tools work alongside the browser
SeaMonkey includes an HTML editor for creating or changing web pages, plus web development tools for related site work.
IRC chat is included as well, adding a real-time communication option to the browser, mail, feed, and page-editing tools.
