I was impressed by the demo videos and blog posts about Firefox OS and decided to try it on my phone Nexus S. Searched for Nexus S ROM and found one here. (TODO: Try building latest version of Firefox OS)
Installation went smooth, followed the documentation from here.
Installing Firefox OS on my Nexus S. Fingers crossed :)— Aravinda (@aravindavk) November 18, 2012
Booting is superfast and Unicode rendering is awesome, adding new fonts also easy. I just used adb (Android Debugger) to push the font from my system.
I took screenshots using ADB and ffmpeg.
./adb pull /dev/graphics/fb0 ffmpeg -vframes 1 -f rawvideo -pix_fmt rgb32 -s 480x800 -i fb0 ~/firefoxos_screenshots/s1.png

Used it for a day and changed it back to Cynogenmod since it was not yet ready for day to day use.
Hoping to learn more about Firefox OS in Firefox OS App Days.
