3.  Firefox OS is an open source mobile operating
system from Mozilla, based on LINUX and
powered by Mozilla's Gecko technology.
 On July 25, 2011, Dr. Andreas Gal, Director of
Research at Mozilla Corporation , announced the
"Boot to Gecko" Project (B2G) on the Mozilla
 Firefox OS. Referred to as Boot 2 Gecko or B2G
 Simply it's a Web App transformed in User
Interface for your Smartphone
History

4.  The idea behind Firefox OS is simple: building apps for
the mobile web using exactly the same tools and
languages as the desktop web.
 Firefox OS is simple to create and work on. It is
completely based on HTML5 and CSS3 just like a browser
running on your phone.
 Bringing The Boot to Gecko project was launched to
enable the Open Web as a platform for mobile devices..
Introduction
 Firefox OS is launched by mozilla in july,2013 . An entirely
web based mobile platform

5. Firefox os Architecture

6. Gaia
• The user interface of the Firefox OS platform
• It is implemented entirely using HTML5, CSS3 and
JavaScript which runs on Gecko and make use of
JavaScript APIs exposed by it
• It also provides basic apps like Browser, Calendar,
Calculator, Camera, Email, Radio, Music…

7. • The application runtime.
• Boot-to-Gecko is an environment to run
apps written using HTML5, CSS3, and
JavaScript
• It implements APIs to access hardware
resources like battery, camera, Bluetooth,
etc

8. Gonk
• A lower level OS of the Firefox OS
• It consists of Linux kernel and user space Hardware
Abstraction Layer (HAL)
• Implements common-open source libraries: Linux,
libusb, bluez, etc
• Some of the other parts of HAL are shared with
Android Project: GPS, Camera, etc
• The APIs used in Gecko are provided by Gonk

9. • When a Firefox OS is turned on, execution begins
in the primary bootloader and at the end
execution is handed off to Linux Kernel
• The bootloaders usually display the first splash
screen seen by the user during device startup;
this is typically a vendor logo
• The bootloader implement flashing an image to
the device. Different device use different
protocols; most phones use the fastboot protocol
Working of FireFox OS

10. • But the Samsung Galaxy SII uses the ordin
protocol
• Now, a userspace init process is launched, as it is
in most UNIX-like Operating syestems
• Once the init process is launched, the Linux kernel
handles system calls
• Many hardware features are exposed to userspace
• For example, here’s a code snipped that reads the
battery state in Gecko

11. If Android is free, then why this?
• Anyone can download Android source and put it on a
device, but companies that want to make and sell Android
devices are probably going to have to negotiate a patent
licensing arrangement with Microsoft.
• Basically all device makers except Google has inked a deal
with it to protect themselves against possible patent
infringement suits.
• Google also has preferred partners who get early looks at
Android while its in development, so they can have their
products ready sooner.
• Firefox OS has none of that.

12. Existing Techniques
 Device specific software
 Take it or leave it policies
 Customer Relationship=By Store
 Needs high end devices to run
efficiently
 The cost is too high
 Developers can write Apps and
Services for one platform-the web
 More developers than any other
platform because Apps based on
HTML5
 8 Million apps developers are
available for HTML5

13. DISADVANTAGES
ADVANTAGES
• It consumes low battery, mobiles using this os and have great battery
backup
• It runs smoothly on low hardware devices unlike android and ios
• As it runs good on low end devices it is very affordable as compare to other
os
• And it gives us a smartphone experience at very low cost
• Your phone never gets absolute because web is the native platform and
versions of apps will run easily on your older hardware
• Firefox os is in developing stage right now .so some apps, features are yet to
be developed like Watsapp is not directly available [connecta2]
• Firefox os is not yet available in big company devices like samsung,
nokia, etc

14. Applications
• Growing numbers of APPLICATIONS. Apps can be developed
freely.
• Ease access through default firefox OS MARKETPLACE.
• Existing development tools can use to make applications
• Firefox OS is totally OPEN-SOURCE under Mozilla Foundation's
motivation.
• Optimize apps (and web rendering!) for low-end devices
• Mobile companies which are producing firefox os mobiles are
ZTE ,ALcatel , SONY ,LG and INTEX

15. Conclusion
 From this we conclude that Firefox OS phones
are different.
 They’re made by a huge global community and
are the only smartphones that understand and
deliver what you want and need.
 It is easier to make an applications in Firefox OS
than any other OS.
