Firefox OS

We created Firefox OS to build the Web as the platform for mobile devices. That includes implementing new Web standards that aren't restricted by the rules of existing proprietary platforms. As with all Mozilla projects, Firefox OS is based entirely on open standards and the source code is accessible to all.

Bringing the Open Web to mobile devices
Firefox OS enables the Open Web as a platform for mobile devices. We’re making innovation possible by driving the development of new Web standards.

New Web standards
Firefox OS will produce an implementation of these new Web standards to free mobile platforms from the encumbrances of the rules and restrictions of existing proprietary platforms.

Freedom from proprietary mobile platforms
We're collaborating with OEMs and carriers directly, giving them more influence to meet the specific needs of their users and market. Users and developers aren't locked in to one platform, so they can access their info and use apps across multiple devices.

Customization for OEMs and operators
OEMs and operators will be able to provide content and services across their entire device portfolio, regardless of OS. And they will be able to customize user experiences, manage app distribution and retain customer attention, loyalty and billing relationships.

Firefox for Android

Based on the same principles and technologies as our desktop browser, Firefox for Android is fast, smart, safe and full of innovations that let you type less, browse more and get to the Web quickly and easily. Our latest version includes improved performance, the latest privacy and security features and a redesigned look and feel.

Firefox for Android is Mozilla's mobile web browser. It's recently been rewritten to use Android's native UI, making it faster, leaner and more responsive. It provides support for powerful APIs to access device capabilities such as the camera and telephony stack.

Apps on the Web

We're bringing our core values – openness, freedom, user choice – to the world of apps and giving developers with full control over content, functionality and how apps are distributed, including access to hundreds of millions of Firefox users through the Mozilla Marketplace.

Take your Firefox anywhere. Firefox for Android is built on the same technology platform as Firefox for desktop computers, just optimized for browsing on a mobile device. Check out the new and improved features, known issues, and frequently-asked questions.
