Although large parts of the original Communicator code, including the layout engine and front-end related codes, were abandoned shortly thereafter, the Mozilla Organization eventually succeeded in producing a full-featured Internet suite that surpassed Communicator in features, stability and degree of standards compliance.

The Foundation is a non-profit organization composed primarily of developers and staff from mozilla.org and owns the Mozilla trademark (but not the copyright to the source code, which is retained by the individual and corporate contributors, but licensed under the terms of the GPL and MPL).

It received initial donations from AOL, IBM, Sun Microsystems, Red Hat, and Mitch Kapor.

[4] However, the Mozilla Foundation emphasized that they would provide infrastructure for community members who wished to continue development.

To avoid confusing organizations that still want to use the Mozilla Suite, it was announced that the new, community-developed product would be named "SeaMonkey", with version numbers that start at "1.0".

Mozilla supported tabbed browsing, which allows users to open multiple Web pages in the same browser window.

With this feature enabled, a user could simply begin typing a word while viewing a Web page, and the browser automatically searched for it and highlighted the first instance found.

This feature allowed users to access their bookmarks from the location bar using keywords (and an optional query parameter).

Through extensions (installed via XPInstall modules), users might activate new features, such as mouse gestures, advertisement blocking, proxy server switching, and debugging tools.

Additionally, Mozilla stored most of its preferences in a list that users could access by typing about:config in the address bar.

Mozilla had extensive support for most basic standards at the time including HTML, XML, XHTML, CSS, JavaScript, DOM, MathML, DTD, XSLT and XPath.

Later versions of the suite supported the element as well as the marquee tag, originally created by rival Internet Explorer.

Among its key features were the use of the sandbox security model, same origin policy and external protocol whitelisting.

Also, access to the source code of Mozilla Firefox, internal design documentation, forum discussions, and other materials that could be helpful in finding bugs were available to anyone.

The policy restricts access to a security-related bug report to members of the security team until after Mozilla has shipped a fix for the problem.

Because of the Foundation's plan to switch development focus to standalone applications such as Firefox and Thunderbird, many new features and enhancements were not available for Mozilla.

SeaMonkey, a community-driven Internet suite that is based on the same source code, is pursued by those that appreciated Mozilla's feature set.
