libxul-dev 1.8.1.16+nobinonly-0ubuntu1 (i386 binary) in ubuntu karmic

 This library provides an API for XUL applications and Gecko embedders.
 The Gecko engine is the core of the mozilla.org applications such as
 Firefox, Thunderbird or SeaMonkey.
 .
 Gecko features include XPCOM, networking, DOM editing and transaction
 support, XBL, XUL, SVG, XSLT, XML Extras (XMLHttpRequest and DOMParser),
 Web Services (SOAP), accessibility support, IPC services, gtkmozembed, etc.
 .
 Install this package if you wish to embed the Gecko engine in your
 program or want to develop XPCOM components.
 .
 This package also provides the Xulrunner Software Development Kit in the
 same form as the one you may find on mozilla.org in /usr/lib/xulrunner/sdk.
 .
 It also contains the JavaXPCOM interfaces and their sources.
