Mozilla will use the code to host a new open source project called Tamarin to accelerate the development of a standards-based approach for creating rich and engaging web applications.
As of today, developers working on SpiderMonkey will have access to the Tamarin code in the Mozilla CVS repository, with contributions to the code managed by a governing body of developers from both Adobe and Mozilla.
"Web developers now have a high-performance, open source virtual machine for building and deploying interactive applications across Adobe Flash Player and the Firefox web browser.
"We are excited about joining the Adobe and Mozilla communities to advance ECMAScript."
Kevin Lynch, senior vice president and chief software architect at Adobe, added: "This is a major milestone in bringing together the broader HTML and Flash development communities around a common language, and empowering the creation of even more innovative applications in the Web 2.0 world.
"By working with the open source community we are accelerating the adoption of a standard language for creating and delivering richer, more interactive experiences that work consistently across PCs and mobile devices."
