New Features and Changes

Gecko 1.9.3 alpha introduces new features which can be tested by using this Mozilla Developer Preview. Many of these features are still in development, and while they will likely appear in some future version of Mozilla Firefox, some may be in earlier releases than others.

Alpha 3: 17-March-2010
Performance	An experimental Direct2D rendering backend on Windows is available, turned off by default. For information and instructions on enabling this experimental feature, see Bas Shouten's post.
JavaScript	Significant API improvements are available for JS-ctypes, a foreign function interface for extensions. ctypes.jsm now supports complex types including structures, pointers, and arrays. See Dan Witte's post for more information.
Stability	Mozilla now uses an infallible allocator: if a request for memory cannot be fulfilled, the allocator aborts. This allows for simplification of the Mozilla code, as well as preventing a class of security errors with unchecked null pointers. See bug 441324 for details.
Plugins	Additional fixes for multi-process plugins:   crash and hang fixes; the Foxit Reader and Octoshape plugins work correctly; Performance improvements in the delivery of network streams.

We are interested in feedback on any bugs or missing capabilities in these new features. Some of the changes will affect web and platform compatibility. For detailed information about compatibility changes in Gecko 1.9.3, please read Upcoming Firefox features for developers.
