New features in Firefox 4 beta

HTML5 Support

A new HTML5 parser and full support for web video, audio, drag & drop, and file handling means Firefox 4 is ready to run the best web apps of both today and tomorrow.

Crash Protection

Firefox provides uninterrupted browsing for Windows, Linux, and now Mac when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins. If one of these commonly-used plugins crashes or freezes, it won’t affect the rest of Firefox. Instead, you can simply reload the page to restart the plugin and try again.


Sites can now keep attackers from intercepting sensitive data while accessing the site by telling Firefox to automatically establish secure connections to their servers (https).


Firefox can now better manage JavaScript objects with Compartments, offering improved cache utilization and garbage collection mechanisms for better security, memory management and overall performance.

Full Hardware Acceleration

Experience super-fast graphics acceleration with Direct2D and Direct3D on Windows, XRender on Linux and OpenGL on Mac, now enabled by default, on all supported hardware.

WebM and HD Video

As pioneers of HTML5 video standards, Firefox also supports the WebM format so you can watch open HD quality video.

Protecting Your Privacy

Firefox puts your privacy first, fixing flaws in some web standards that allow bad guys to snoop around and expose your browser history.

New JS values

Changes to the C++ representation of JavaScript values allow Firefox to execute heavy, numeric code more efficiently, resulting in cleaner graphics and a better browsing experience.

Multi-touch Support

Firefox now integrates multi-touch support for Windows 7, enabling you to interact with your browser in a whole new way.

Retained layers

Experience super fast scrolling on complex web pages. Simply awesome.


Firefox starts up even faster thanks to XPCOM module improvements that pave the way to a better extensions framework.
