Firefox OS[4] (project name: Boot to Gecko, also known as B2G)[5] is a Linux-based open source operating system for smartphones and tablet computers being developed by Mozilla. It is designed to allow HTML5 applications to communicate directly with the device's hardware using JavaScript and bridge open web API's.[5] It has been demonstrated on Android-compatible smartphones[6][7] and Raspberry Pi.[8]

ZTE confirmed at CES 2013 that they will ship a smartphone with Firefox OS.[9]

History [edit]

On July 25, 2011, Dr. Andreas Gal, Director of Research at Mozilla Corporation, announced the "Boot to Gecko" Project on the mozilla.dev.platform mailing list.[10] The project proposal was to "pursue the goal of building a complete, standalone operating system for the open web" in order to "find the gaps that keep web developers from being able to build apps that are – in every way – the equals of native apps built for the iPhone [iOS], Android, and WP7 [Windows Phone 7]."[10] The announcement identified these work areas: new web APIs to expose device and OS capabilities such as telephone and camera, a privilege model to safely expose these to web pages, applications to prove these capabilities, and low-level code to boot on an Android-compatible device.

This led to much blog coverage.[11][12] According to Ars Technica, "Mozilla says that B2G is motivated by a desire to demonstrate that the standards-based open Web has the potential to be a competitive alternative to the existing single-vendor application development stacks offered by the dominant mobile operating systems."[13]

In July 2012, Boot to Gecko was rebranded as 'Firefox OS',[14] after Mozilla's well-known desktop browser, Firefox, and screenshots began appearing in August 2012.[15]

In September 2012 analysts Strategy Analytics forecasted Firefox OS would account for 1% of the global smartphone market in 2013 – its first year of commercial availability.[16]

In February 2013 Mozilla announced plans for global commercial roll-out of Firefox OS.[17] Mozilla announced at a press conference before the start of Mobile World Congress in Barcelona that the first wave of Firefox OS devices will be available to consumers in Brazil, Colombia, Hungary, Mexico, Montenegro, Poland, Serbia, Spain and Venezuela. Firefox have also announced that LG Electronics, ZTE, Huawei and TCL Corporation have committed to making Firefox OS devices.[18]

Demonstrations [edit]

At Mobile World Congress 2012, Mozilla and Telefónica announced that the Spanish telecommunications provider intended to deliver "open Web devices" in 2012 based on HTML5 and these APIs.[19] Mozilla also announced support for the project from Adobe and Qualcomm, and that Deutsche Telekom’s Innovation Labs will join the project.[20] Mozilla demonstrated a "sneak preview" of the software and apps running on Samsung Galaxy S II phones (replacing their usual Android operating system).[6][21] In August 2012, a Nokia employee demonstrated the OS running on a Raspberry Pi.[22]

Firefox OS is compatible with devices including: Otoro, PandaBoard, Emulator (ARM and x86), Desktop, Nexus S, Nexus S 4G, Samsung Galaxy S II, and Galaxy Nexus.[23]

In December 2012, Mozilla rolled out another update and released Firefox OS Simulator 1.0 which can be downloaded as an add-on for Firefox.

Goals [edit]

[icon] This section requires expansion. (March 2013)

When interviewed, Mozilla’s Director of Research Andreas Gal characterised the current set of mobile OS pages as "walled gardens"[25] and presented Firefox OS as more accessible: "We use completely open standards and there’s no proprietary software or technology involved."[25] Gal also said that because the software stack is entirely HTML5, there are already a large number of established developers.[25] This assumption is employed in Mozilla's WebAPI.[26] These are intended W3C standards that attempt to bridge the capability gap that currently exists between native frameworks and web applications.[27] The goal of these efforts is to enable developers to build applications using WebAPI which would then run in any standards compliant browser without the need to rewrite their application for each platform.

Open web technologies stack [edit]

The initial development work involves three major software layers: Gonk, Gecko, and the HTML5 layer, which includes the Gaia user-interface.[28]

Gonk [edit]

Gonk consists of a Linux kernel and userspace hardware abstraction layer (HAL). The kernel and several userspace libraries are common open-source projects: Linux, libusb, BlueZ, etc. Some other parts of the HAL are shared with the Android project: GPS, camera, among others. Gonk is basically an extremely simple Linux distribution and is therefore a porting target of Gecko; there is a port of Gecko to Gonk, just like there is a port of Gecko to OS X, and a port of Gecko to Android. Since the B2G project has full control over Gonk, the developers can expose interfaces to Gecko that aren't possible to expose on other OSes. For example, Gecko has direct access to the full telephony stack and display framebuffer on Gonk, but doesn't have this access on any other OS.[28]

Gecko [edit]

Main article: Gecko

Gecko is the application runtime of B2G. Gecko implements open standards for HTML, CSS, and JS. Gecko includes a networking stack, graphics stack, layout engine, virtual machine (for JS), and porting layers.[28]

Gaia [edit]

Gaia is the user interface of Firefox OS and controls everything drawn to screen. Gaia includes by default implementations of a lock screen, home screen, telephone dialer and contacts application, text-messaging application, camera application and a gallery support, plus the classic phone apps: mail, calendar, calculator and marketplace. Gaia is written entirely in HTML, CSS, and JavaScript. It interfaces with the operating system through Open Web APIs, which are implemented by Gecko. Because it uses only standard web APIs, it can work on other OSes and other web-browsers.[28]

Criticisms [edit]

Chris Ziegler of the technology blog The Verge wrote that it will take app distribution to pre-iPhone era, requiring application developers to deal with multiple carriers and their app stores.[29][30] But at the Mobile World Congress, Gary Kovacs, the CEO of Mozilla, said that the devices matter less than what they're able to run, apps make or break a mobile platform these days, not hardware, and the advantage is that they don't have to install an app to use it. Mozilla is making the most of this with the search functionality built into Firefox OS, a core feature of the platform.[31] Janne Lindqvist, a mobile security researcher at the Rutgers University Winlab, expressed concerns related to the discovery mechanism of a web-based platform, but a Mozilla spokesperson has stated that they are "requiring developers to package downloadable apps in a zip file that has been cryptographically signed by the store from which it originated, assuring that it has been reviewed," additionally "apps coming back from search are given only limited access to device programming interfaces and applications, unless the user grants permission for further access."[32]
