Mozilla Composer

Mozilla Composer running on Linux

Mozilla Composer is the former free and open-source HTML editor and web authoring module of the Mozilla Application Suite (the predecessor to SeaMonkey). It was used to create and to edit web pages, e-mail, and text documents, and available for Windows, macOS and Linux. Composer was a graphical WYSIWYG HTML editor to view, write and edit HTML source code.[1]

In September 2008 Daniel Glazman announced a new WYSIWYG HTML editor, BlueGriffon, written from scratch and based on Mozilla Gecko and XULRunner.[2]

SeaMonkey, the community-driven successor to Mozilla Suite, includes an HTML editor named Composer that is developed from the Mozilla Composer code contained in the original Mozilla Suite.[1]

Nvu (pronounced "N-view") is a WYSIWYG HTML editor,[3] based on Mozilla Composer. It is intended to be an open-source alternative to proprietary software like Microsoft Expression Web and Adobe Dreamweaver. As a WYSIWYG editor, it is designed to be easy for novice users, and does not require any knowledge of HTML or CSS to use. It runs on Mac OS X, Windows and Linux and incorporates Cascading Style Sheets support and other improvements from software company Disruptive Innovations. Nvu was the brainchild of Kevin Carmony, CEO for Linspire, who wanted an easy-to-use, WYSIWYG HTML editor for Linux users.[4] Under Carmony's direction, Linspire started and sponsored Nvu, hiring Daniel Glazman, former Netscape Communications Corporation employee, to be the lead developer.[4]

### Development

The original plan in June 2005 was to merge back the numerous changes into Mozilla Composer's source code tree. Since then the Mozilla Suite has been discontinued (then reintroduced as SeaMonkey), and no one has merged the Nvu code back into Composer.

### Standards compliance

Nvu CSS editor

Nvu complies with the W3C's web standards. By default, pages are created in accordance to HTML 4.01 Transitional and use CSS for styling, but the user can change the settings and choose between:

* Strict and transitional DTD's
* HTML 4.01 and XHTML 1.0
* CSS styling or the old `<font>` based styling.

The application includes a built-in HTML validator, which uploads pages to the W3C's HTML Validator and checks for compliance.

### Shift to KompoZer

Daniel Glazman, the lead developer of Nvu, announced on September 15, 2006, that he had stopped official development on Nvu and that he was developing a successor as a Mozilla.org project. It is written from scratch and based on Mozilla trunk Gecko 1.9 and XULRunner. PHP and CSS would be supported. A community-driven fork, KompoZer, maintains Nvu codebase and fixes bugs until a successor to Nvu is released. Glazman's project is called BlueGriffon.

## KompoZer

Kompozer

KompoZer 0.7.10 editing Wikipedia main page

Original author(s)| Fabien Cazenave
Platform| Cross-platform
Type| HTML editor
License| MPL/GPL/LGPL tri-license
Website| kompozer.net

KompoZer is a discontinued open source WYSIWYG HTML editor based on the Nvu.[5] KompoZer was forked as a community-driven project with development coordinated through SourceForge.

KompoZer's WYSIWYG editing capabilities are one of the main attractions of the software. In addition, KompoZer allows direct code editing as well as a split code-graphic view.

The most recent version is KompoZer 0.8 beta 3, released February 2010, using Gecko 1.8.1. The stable version was 0.7.10, released in August 2007. The only regular developer said in June 2011 that development "is stalled at the moment".[6]

As a 32-bit application, it is no longer supported on macOS Catalina and later versions.

### Standards compliance

KompoZer complies with the W3C's web standards. By default, pages are created in accordance to HTML 4.01 Strict and use Cascading Style Sheets (CSS) for styling, but the user can change the settings and choose between:

* Strict and transitional DTD's
* HTML 4.01 and XHTML 1.0
* CSS styling or the old `<font>` based styling.

The application can call on the W3C HTML validator, which uploads pages to the W3C Markup Validation Service and checks for compliance.
