Blame cord cutters. Or cell phones. Or the rise of great original content. Whatever the reason, people now have an obvious and insatiable hunger for streaming online video and that demand is only increasing.

Whether it’s their favorite Netflix shows or must-see live sports, people want to watch more video. They want it now, on all their devices — computer, laptop, tablet and mobile — and they want it to be high quality. …


We wanted Firefox to be faster. Much faster. But it’s not enough to just be fast — our goal was to make an overall better browser for the user. Why have all that speed if you’re not going to put it where the user wants it most?

I first shared our vision for “Project Quantum” last year. That’s the code name we used for our work to embrace a truly next generation architecture for Firefox, and for the web. Here we are one year later and today we celebrate the release of a new Firefox, the most powerful version of…


Mozilla Developer Roadshow events are fun, informative sessions for people who build the Web. Over the past eight months we’ve held thirty-six events all over the world sharing the word about the latest in Mozilla and Firefox technologies. Now we’re heading to Asia with the goals of finding local experts and connecting the community. Some of our most successful moments have been when we were able to bring local event organizers together to forge lasting relationships. Our first Asia event is in Singapore at the PayPal headquarters on September 19. (Check here for a full list of the cities.)

With today’s release of Firefox, we are the first browser to support WebAssembly. If you haven’t yet heard of WebAssembly, it’s an emerging standard inspired by our research to enable near-native performance for web applications.

WebAssembly is one of the biggest advances to the Web Platform over the past decade.

This new standard will enable amazing video games and high-performance web apps for things like computer-aided design, video and image editing, and scientific visualization. Over time, many existing productivity apps (e.g. email, social networks, word processing) and JavaScript frameworks will likely use WebAssembly to significantly reduce load times while simultaneously…


Over the past year, our top priority for Firefox was the Electrolysis project to deliver a multi-process browsing experience to users. Running Firefox in multiple processes greatly improves security and performance. This is the largest change we’ve ever made to Firefox, and we’ll be rolling out the first stage of Electrolysis to 100% of Firefox desktop users over the next few months.

But, that doesn’t mean we’re all out of ideas in terms of how to improve performance and security. In fact, Electrolysis has just set us up to do something we think will be really big.

We’re calling it…


Mozilla Pushes the Web to New Levels as a Platform for Games

The Web is the platform for game development and we‘ve shown it in action at this year’s Game Developer Conference in San Francisco. Powerful new capabilities continue to emerge and gain mindshare with developers and gamers alike as the open Web games stack reaches ubiquity.

  • Technologies pioneered by Mozilla, such as WebGL, WebVR and asm.js are all gaining momentum.
  • Today, WebAssembly, the next evolution of asm.js, is available as an experiment for testing in Firefox Nightly.
  • Launched at this past GDC, Open Web Games is a site for developers and browser…


These days it takes a diverse and complex collection of components to power a web browser. It’s fair to think of all those parts coming together as a single piece of machinery, and we often talk about our web platform as an “engine”. Mozilla’s web engine is known as “Gecko”, and is something we’ve been working on for over two decades.

Originally web engines existed purely to let you build a web browser — a stand-alone application you used on some computer whenever you wanted to access the web, just as you are doing now — and the web was…
