The following is a list of all known active applications that are built using Mozilla technologies. This list is likely to be incomplete since we think there are many dark matter projects that we don't know about. If you have information about a new project or extra information about an existing project, please feel free to update this page.

A list of former Mozilla-based applications is also available.
