ZTE, one of China's most prominent handset makers, plans to launch smartphones running the new Firefox OS early next year.

Speaking today to reporters in China, the company said it will launch handsets running Firefox OS in the first quarter of 2013. According to the Wall Street Journal, which was in attendance at the press event, the company didn't say how many Firefox OS-based smartphones it plans to launch, and offered no further details on the devices.

Mozilla announced its ZTE partnership over the summer. At that time, the company also named the operating system Firefox OS. The … Read more

Mozilla has begun building a new technology called IonMonkey into Firefox to improve its JavaScript performance.

High JavaScript performance is essential in today's hotly competitive browser market, because JavaScript is the language behind complicated Web sites and Web apps such as Google Docs and Facebook. IonMonkey has now been packaged into the "nightly" version of Firefox 18 for hardcore developers; that version is scheduled to become the mainstream version of the browser early in 2013.

IonMonkey is what's called a just-in-time compiler, or JIT for short. In olden days, JavaScript would run line by line in … Read more

The Internet Engineering Task Force has standardized the Opus audio compression technology as RFC 6716.

The move paves the way for much broader use of Opus for anything from playing music to online voice chats. Opus is what's called a codec because it defines how to encode and decode a stream of data for more efficient storage or transmission.

"Opus is the first state-of-the-art, free audio codec to be standardized. We think this will help us achieve wider adoption than prior royalty-free codecs," Jean-Marc Valin, a Mozilla employee and author of Opus, said in a blog post today. … Read more

Browser maker Mozilla has patched a bug in the latest major version of Firefox that could have exposed the websites of those using the "Private Browsing" mode.

"Private Browsing," a feature implemented in most modern browsers, allows users to browse the Web without leaving any trace of the websites visited on the user's computer.

But shortly after the latest Firefox release was dished out to end-users, a bug report was filed to claim that any site visited while in the privacy-conscious mode "could be found through manual browser cache inspection," according to Mozilla's bug-reporting site Bugzilla.… Read more

New images have hit the Internet and purport to show what could be the design for Mozilla's upcoming Firefox OS Marketplace.

Engadget published photos yesterday of what it claims is the app store for Firefox's mobile operating system. The images show a small listing of apps, including Solitaire and Word Wars. Several app categories are listed, including business, games, and books and reference.

According to Engadget, once users click on an application to get details, they'll find a rating and the option to submit a review to the community.

Mozilla gave Firefox OS its name back in July. … Read more

Please note that the First Look video below is still applicable to Firefox 15, as is this Firefox How To collection, even though it features Firefox 4. A new video will be posted soon.

Review: Mozilla Firefox has undergone an enormous rebirth over the past two years. Since Firefox 4 debuted in March 2011, the browser has been hell-bent on improvements. These have come in large part on the rapid-release cycle, which sees a new version of Firefox every six weeks. Many people like them, but a vocal minority has pooh-poohed the increase in version numbers. That's hardly a … Read more

As with many tech code-names, MemShrink doesn't sound particularly exciting. And yet, the memory leak-managing project at Mozilla finally sees some of its biggest changes reach the vast majority of people using Firefox with today's major update.

Mozilla expects that the new Firefox 15 for PCs (download for Windows | Mac | Linux) finally will put an end to the multitude of memory-managing issues that have plagued Firefox for years. As we noted in July when Firefox 15 went beta, the MemShrink project has spent much of its time fixing how the browser handles add-ons that contribute to memory problems. … Read more

For more than three years, Skype has worked to improve online audio through involvement in a project now called Opus. But perversely, Skype's new owner, Microsoft, is undermining Opus just as a Web standards effort is poised to carry it into the mainstream.

Opus is an audio "codec" -- technology to encode and decode media streams for efficient transmission over the Internet or storage on computing equipment. Opus backers besides Microsoft's Skype division include Google, Opera, and Mozilla.

Opus has a lot of potential to improve online audio, something that's increasingly important as more communications … Read more

Mozilla took a big step toward the coming conflict between native apps and Web apps as it introduced Web app support to Firefox 16, which moved to the the developer's Aurora channel last Friday.

The Web app support in Firefox 16 Aurora (download for Windows, for Mac, for Linux, and for Android) means that when the Mozilla Marketplace opens to the public -- likely to be sometime before the end of 2012 -- people will be able to run Web-based apps through any iteration of Firefox. This is part of Mozilla's "Kilimanjaro" project, syncing up the … Read more
