Here's adfad666 original post qoute: 
( http://forum.xda-developers.com/showthread.php?t=1994568 )

"You may have noticed I've been rather quiet recently. I've been spending my time trying to get Firefox-OS working. It's based on Android's HAL so it should work, but currently the Mozilla part is still not compatible with ARMv6 devices. Nothing I try will get it to boot.

However going through the build files, I came across some files that are quite different to CyanogenMod, potentially we may have been creating inferior builds since even the Gingerbread days!!!
