Adobe Delivers Its Flash Player Code to Mozilla

Adobe and the Mozilla Foundation say that Adobe has contributed source code for the ActionScript Virtual Machine, the powerful standards-based scripting language engine in Adobe Flash Player, to the Mozilla Foundation. Mozilla will host a new open source project, called Tamarin, to accelerate the development of this standards-based approach for creating rich and engaging Web applications. The Tamarin project will implement the final version of the ECMAScript Edition 4 standard language, which Mozilla will use within the next generation of SpiderMonkey, the core JavaScript engine embedded in Firefox, Mozilla's free Web browser. As of today, developers working on SpiderMonkey will have access to the Tamarin code in the Mozilla CVS repository via the the project page. Contributions to the code will be managed by a governing body of developers from both Adobe and Mozilla.

Tamarin implements the ECMAScript standard used by languages such as JavaScript, Adobe ActionScript, and Microsoft JScript, the primary languages developers use for building rich Internet applications. Adobe and Mozilla are both active participants in the ECMA International Programming Language technical committee (TC39-TG1) developing the ECMAScript Edition 4 (ES4) standard.

Adobe's most recent virtual machine for ActionScript 3.0, a core component of Adobe Flash Player 9 released in June 2006, was built from the ground up to offer breakthrough performance and features, including more efficient memory utilization, faster application start-times, improved debugging and full runtime error reporting. Adobe Flash Player is installed on over 700 million Internet-connected PCs and mobile devices worldwide. The ActionScript Virtual Machine features a Just In Time (JIT) compiler that translates ActionScript bytecode to native machine code for maximum execution speed. Now developers can leverage existing skills to quickly and easily build complex rich Internet applications increasingly required as users demand more interactive Web experiences.
