Crossfire is a Firebug extension which implements a JSON protocol to allow remote clients (like an IDE or code editor) to connect to Firebug.

Who is using Crossfire ?

One of the main goals of Crossfire is to provide a simple and straight-forward method for tools in other processes to obtain the same kind of information that Firebug has about the Web pages the user is debugging.

  • The Firebug Working Group is currently planning to use Crossfire in future versions of Firebug as a solution for the out-of-process plugin architecture of Firefox 4.
  • Webtools JavaScript Development Tools from Eclipse is using Crossfire to provide Firebug and Internet Explorer debugging capabilites; JSDT Debug Wiki
  • The 8.0 beta version of IBM's Rational Application Developer is using Crossfire to enhance their existing Firebug integration. RAD Open Beta Demo video
  • The 4D Wakanda Team is implementing a Crossfire client into the Server-Side JavaScript Debugger of the Wakanda Studio and a Crossfire server into the JavaScript engine of the Wakanda Server (based on webkit): Wakanda

Getting Started

Getting started with Crossfire contains some helpful information for getting started. This is mostly intended for developers interested in building tools that connect to Crossfire, and assumes some familiarity with Firebug and Firefox extensions.

There are pre-built versions of Crossfire available:

Connecting Firebug in Firefox to another Firebug in Firefox is a tutorial that explains how to connect the Crossfire client and Crossfire server by running to separate Firefox processes.

Running Crossfire Tests explains how to execute the various test suites for Crossfire.
