As you may know, KompoZer is an open-source WYSIWYG (What You See Is What You Get) and HTML editor, based on Nvu, which is discotinued. KompoZer is maintained by the community now, since it was dropped from Debian.
This is how to install KompoZer on Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal and Ubuntu 12.04 Precise Pangolin.
