Mozilla Made the Web Better for Developers in 2017
2017 was a stellar year for Mozilla. We launched the fastest Firefox ever, rebuilt DevTools, saw support for WebAssembly ship in all four major browsers, and launched open-source virtual reality and speech recognition platforms. Our developer relations team also attended more than 60 roadshow events around the world and saw the MDN Web Docs site nearly double its readership.
It’s a tough act to follow, but we hope to continue the pace in 2018. We have a ton of great open-source tech on the horizon, all of which we’ll cover here and over at the Mozilla Hacks blog. Thanks for sticking with us, and for reading our various publications across the web. We couldn’t have accomplished any of it without the support of the worldwide developer community.

Firefox ran on the same engine for more than a decade, and at the beginning of 2017, it showed. The browser needed a boost, and Mozilla engineers gave it one. Working with the Servo project, they rewrote the browser’s engine using new core technologies. The first being Rust, an all-new programming language written to take advantage of the latest multi-core processors. Then there’s Servo, the parallel engine built on Rust. And Stylo (Quantum CSS) to again take advantage of multi-core processors. Put it all together and you get a browser that’s light years ahead of the previous version and can outperform other browsers in certain tasks. It took years, multiple teams of engineers, and more than four million lines of new code.
For an in-depth look at how it all works, take a look at Mozilla engineer Lin Clark’s comprehensive post at Mozilla Hacks.
Wagner wrote an in-depth history of WebAssembly for IEEE Spectrum magazine. In it, he tells the tale of using WebAssembly to run game engines Unity and Unreal in Firefox.
A-Frame and WebVR
Virtual reality on the web has been the future for about 25 years now, but those dreams didn’t become reality until 2017. This year, VR standards and frameworks took a big step forward, making it easier than ever to create VR experiences and share them on a variety of devices, from headsets to smartphones and browsers. Mozilla helped promote two major virtual reality web platforms: A-Frame and WebVR. Now major browsers support the standards, which means developers are free to create immersive experiences that run on almost any computer or device. And, because they’re based on standards, they’re easy to use. In fact, a member of our team created a virtual reality experience in less than a day and wrote about it here.
With the introduction of Firefox Quantum, virtual reality on the web is, well, a reality. Mozilla engineer Salva wrote a wonderful piece for Mozilla Hacks explaining how it all works.
Project Common Voice
Siri, Cortana, Echo, Google Home — virtual assistants are the future. But the voice recognition data they’re built on is mostly proprietary. That’s why Mozilla launched its open speech initiative in 2017, to try to level the playing field. Common Voice is an open-source voice recognition project for everyone. Here’s how it works: Contributors read phrases aloud to the Common Voice website to help the AI learn how to understand spoken language. They can also validate Common Voice transcriptions to ensure the AI is on the right path. All the data is free and available for researchers building voice apps.
Right now the site is in English, but other languages are forthcoming. Mozilla head researcher Sean White wrote a brilliant piece about Common Voice for the main Mozilla blog here. Head over to the Common Voice site to contribute your own voice.
Mozilla developers toured the world in 2017 to help promote open standards and new technologies, including WebVR, A-Frame, and WebAssembly. They visited more than 60 developer roadshow events worldwide.
Mozilla Developer Network
In 2017, more than 8,000 developers contributed to 80,000 pages of content on the Mozilla Developer Network. Mozilla also teamed with Microsoft, Google, and other industry leaders to greatly expand the scope of MDN web docs. It’s a huge collaboration and one that we all hope will make the web a better place for developers and consumers alike.
So what’s next for Mozilla? We’re going to keep making Firefox faster and more powerful, which means fine-tuning WebAssembly and other core technologies. We hope to help WebVR and A-Frame become standards for rich content on the web. We will continue to champion open-source voice and machine learning projects. In short, we’ll keep working to ensure the web remains open and accessible for everyone.
