Mozilla is a non-profit organization driven by the mission of promoting openness, innovation and opportunity on the Web. We work as a global community to build products like Firefox that embody the values of our mission and create more user control, flexibility and innovation on the Web.

In the nearly 10 years since we first launched Firefox, it has grown to be the trusted and most customizable browser of choice for half a billion people worldwide.

We reimagined and redesigned Firefox to reflect how you use the Web today and we are excited to introduce many features including an elegant and fun design, new menu, customization mode and an enhanced Firefox Sync service powered by Firefox Accounts.

The first thing you’ll notice in Firefox is the beautiful new design that makes it easy to focus on your Web content. The tabs are sleek and smooth to help you navigate the Web faster. It’s easy to see what tab you’re currently visiting and the other tabs fade into the background to be less of a distraction when you’re not using them.

The Firefox menu has moved to the right corner of the toolbar and puts all your browser controls in one place. The menu includes a “Customize” tool that transforms Firefox into a powerful customization mode where you can add or move any feature, service or add-on. This level of Firefox customization puts you in control of your Web experience and is unmatched by any other browser.

The new Firefox Sync service is a safe and easy way to take your Firefox everywhere. Firefox Sync gives you access to Awesome Bar browsing history, saved passwords, bookmarks, open tabs and form data across your computers and mobile Android devices. It is powered by Firefox Accounts and simplifies the setup and device syncing process.

We looked at every piece of Firefox and made everything more enjoyable and easier to use – even bookmarks. You can create bookmarks with a single click and manage them from the same place.

Check out just some of the new features below, and have fun making Firefox yours.

Web Platform and Developer Tools:

Specific asm.js optimizations in Firefox mean it currently runs asm.js-style code faster than any other browser. Using asm.js and Emscripten, we helped Epic Games and Unity add the Web as another export option to their hugely popular game engines without the need for plugins.

Web Audio API: With Web Audio API, developers can now build robust audio engines capable of new features like positional audio and support for effects such as reverb, which can create immersive audio experiences on the Web, which is especially important for game developers.

CSS Flexbox: The integration of CSS Flexbox in Firefox makes it easier for developers to build user interfaces that adapt to the size of the browser window or to create elastic layouts which adapt themselves to the font size. This is helpful when developers are trying to create a consistent user interface to their Website or Web app across desktop and mobile.
