Mozilla releases Firefox 4 beta 7

A new beta version of Firefox 4 hit the web today, and it's packing the new, faster J├ĄgerMonkey JavaScript engine. You can download the new beta here.

A quick look at the accompanying release notes reveals a host of improvements over and above the updated JavaScript engine. For example, WebGL is enabled by default on both Windows and Mac OS X, assuming a Open GL-capable graphics card is available. In addition, Firefox 4 beta 7 adds hardware acceleration for some rendering operations, employing Direct3D 9 on Windows XP, Direct3D 10 on Windows Vista and 7, and OpenGL on Mac OS X.

Moving up from Firefox 3.6? There's a long list of changes that have been made since then: Direct2D hardware acceleration for Windows 7 users, plug-in crash protection, support for HSTS security protocol, Firefox Sync, improved tab management, and a new HTML5 parser, to name a few.

Firefox 4.0 isn't expected to be released in final form until early 2011. In the meantime, beta 7 provides a good opportunity to see where Mozilla is taking its prized possession.
