MDN wants to talk to developers like you:

Build legacy branches

Legacy branches of Firefox OS need multiarch packages installed. Newer operating systems do not have these installed by default. 

Run these commands to enable use on the i386 architecture:

sudo dpkg --add-architecture i386
sudo apt-get update

Run this command to install necessary packages:

sudo apt-get install --no-install-recommends autoconf2.13 bison bzip2 ccache curl flex gawk gcc g++ g++-multilib gcc-4.7 g++-4.7 g++-4.7-multilib git lib32ncurses5-dev lib32z1-dev libgconf2-dev zlib1g:amd64 zlib1g-dev:amd64 zlib1g:i386 zlib1g-dev:i386 libgl1-mesa-dev libx11-dev make zip ia32-libs libxml2-utils lzop openjdk-7-jdk

Run these commands to make gcc-4.7 the default compiler:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 1 
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.7 1 
sudo update-alternatives --set gcc "/usr/bin/gcc-4.7" 
sudo update-alternatives --set g++ "/usr/bin/g++-4.7"
