Mozilla Prepares Its Own Web-Based Operating System

Mozilla has announced today they're effectively working on the development of their own operating system. Mozilla "Boot To Gecko" is basically a Gecko-based competitor to Google's Chrome OS operating system. "Mozilla believes that the web can displace proprietary, single-vendor stacks for application development. To make open web technologies a better basis for future applications on mobile and desktop alike, we need to keep pushing the envelope of the web to include --- and in places exceed --- the capabilities of the competing stacks in question."

Firefox 6 Should Sort Out Linux GPU Acceleration

Mozilla Firefox 4.0 was released in March with many new features, including GPU-based acceleration, but on the Linux side this support was disabled. The Mozilla developers found the Linux GPU driver support to be a problem, even with the open-source solutions. It looks like though by Firefox 6 the Linux GPU acceleration will be in better standing.

Attention Turns To Open-Source Drivers & Firefox

Last week we reported on Mozilla Firefox developers having issues with Linux GPU drivers to the point that the Firefox 4.0 Linux build will not have GPU acceleration enabled by default, but it can be found for Mac OS X and Windows users. Fortunately, to fix the situation, there's now some open-source Mesa/X developers looking into these problems of Firefox GPU acceleration.

Firefox Developers Have Issues With Linux GPU Drivers Too

Mozilla Firefox 4.0 will feature GPU hardware acceleration using OpenGL (or Direct2D/Direct3D under Microsoft Windows) acceleration for WebGL content and even HTML5. This support is there for Windows and Mac OS X, but for Firefox 4.0 the Linux support has been disabled and WebGL is also blacklisted for most drivers. Why? It's the problematic GPU drivers, of course.

Mozilla Thunderbird 3.0 Released, Finally

At long last, Mozilla Thunderbird 3.0 has been officially released.

However, the 3.0 release of this Mozilla mail client should be rather great and does boast many improvements.

Ubuntu's Firefox May Gain JPEG 2000 Support

JPEG 2000, the image file format that has been around for nearly a decade and offers better compression performance and greater flexibility in the code-stream that can allow for higher quality photographs compared to a traditional JPEG, may get a boost on the Linux desktop. JPEG 2000 hasn't seen much adoption in large part because of the lack of web browsers that natively support this JP2 ISO standard, including Firefox. While there was an attempt before to add JPEG 2000 support to Firefox through a Google Summer of Code project, Mozilla developers have largely been opposed to adding this support since this file format is not used enough nor "important enough" to justify the work and face any possible legal threat in implementing this open-source support.
