Adobe is to contribute source code to the Mozilla Foundation as the two organisations aim to establish a standard scripting language. They hope that developers will use this to create interactive applications for Adobe's Flash Player and Mozilla's Firefox browser.
Adobe will participate in Tamarin as well. Adobe's contribution is the largest made to the Mozilla Foundation since its inception, according to the organisations.
The standard scripting language that Tamarin will implement in Firefox is ECMAScript 4, now being developed by standards body Ecma International.
Tamarin's ultimate goal is to "unify" scripting across Firefox and Flash and thus give developers an open source virtual machine for developing and deploying rich, interactive applications across both platforms, according to the organisations.
The effort should yield better compatibility, integration and stability between Flash and Firefox and make it easier for developers to work with the two environments, said Michael Goulde, a Forrester Research analyst.
