XULRunner is a runtime environment developed by the Mozilla Foundation to provide a common back-end for XUL-based applications. It replaced the Gecko Runtime Environment, a stalled project with a similar purpose.
The first stable developer preview of XULRunner was released in February 2006, based on the Mozilla 1.8 code base.
XULRunner is a "technology experiment", not a shipped product, meaning there are no "official" XULRunner releases, only stable builds based on the same code as a corresponding Firefox release.
All XUL-based applications like Mozilla Firefox, Mozilla Thunderbird, Songbird, Flickr Uploadr, SeaMonkey, Conkeror, Sunbird, Miro, Joost, and TomTom Home 2.0 run on XULRunner. Starting with version 3.0, Mozilla Firefox uses a "private" XULRunner, meaning the framework is installed locally in the application directory.
The fourth version of the video game series Simon the Sorcerer, Simon the Sorcerer 4: Chaos Happens, uses XULrunner.
The eMusic website has a download application called eMusic Remote that uses XULRunner.
The Google Adwords Editor uses XULRunner, as does the Evergreen ILS, a free and open-source library automation system.
In addition, the XULRunner package provides access to ActiveX Control functionality previously found in a (now defunct) third-party ActiveX Control built off the Mozilla source code. Applications using this application programming interface (API) may function with XULRunner installed and registered.
Starting with Lotus Notes version 8.5.1, IBM deployed XULRunner to provide Notes client support for XPages applications.
