Mozillabased

Mozillabased is an informal label used to describe software that is built on Mozilla's open-source platform or relies on Mozilla technologies. In practice, Mozillabased applications typically leverage the Gecko rendering engine for web content, use XUL-based user interfaces or XPCOM components, and depend on Mozilla libraries such as NSS for security and NSPR. The term covers both standalone applications packaged with Mozilla tooling (historically via XULRunner) and applications that embed Gecko in other environments.

Licensing and distribution are common considerations for Mozillabased projects. Much code is released under the Mozilla Public License or compatible licenses, though some components may be dual-licensed with GPL/LGPL or released under MPL 2.0. Distributors must observe Mozilla's redistribution rules and include appropriate notices and source code where required.

Notable examples and historical context illustrate the scope of Mozillabased software. SeaMonkey, a long-running Mozilla-based internet suite, combines a browser, email client, and other tools and remains one of the best-known Mozillabased projects. Thunderbird is another prominent example, providing an email client built on Mozilla code. Historically, projects such as Camino and Prism used Mozillabased technologies (and XULRunner) for Mac browser development and web-app hosting, though both have since been discontinued. In contemporary development, Gecko is often accessed through GeckoView for embedding in mobile apps, while some projects rely on Firefox components rather than building entirely new Mozillabased stacks.

Current status and usage vary by project, but Mozillabased software remains a reference point for applications that depend on Mozilla’s rendering, UI paradigms, and libraries rather than building from entirely separate engines.
