'''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 page]]s, [[e-mail]], and text documents, and available for [[Windows]], [[macOS]] and [[Linux]]. Composer was a [[graphical user interface|graphical]] [[WYSIWYG]] [[HTML editor]] to view, write and edit [[HTML]] source code.<ref name="~1">[http://www.seamonkey-project.org/ The SeaMonkey® Project]. Seamonkey-project.org. Retrieved on 2013-07-17.</ref>

In September 2008 [[Daniel Glazman]] announced a new [[WYSIWYG]] HTML editor, [[BlueGriffon]], written from [[Scratch (programming language)|scratch]] and based on Mozilla [[Gecko (layout engine)|Gecko]] and [[XULRunner]].<ref>{{Cite web |url=http://www.glazman.org/weblog/dotclear/index.php?post/2008/09/29/BlueGriffon |title=BlueGriffon Announcement |access-date=2021-07-08 |archive-date=2008-12-20 |archive-url=https://web.archive.org/web/20081220055219/http://www.glazman.org/weblog/dotclear/index.php?post/2008/09/29/BlueGriffon |url-status=dead }}</ref>

[[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.<ref name="~1" />
