and JavaScript which runs on Gecko and make
use of JavaScript APIs exposed by it

Calendar, Calculator, Camera, Email, Radio,

Linux, libusb, bluez, etc

9. Working of Firefox OS
• 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

10. Working of Firefox OS
• But the Samsung Galaxy SII uses the ordin
protocol
• Now, a userspace init process is launched, as it
is in most UNIX-like OS
• At this point in execution, the only mounted
“disk” is a RAM disk
• Once the init process is launched, the Linux
kernel handles system calls

11. Working of Firefox OS
• Many hardware features are exposed to
userspace through sysfs
• For example, here’s a code snipped that reads
the battery state in Gecko
