carlosdark54 was able to figure it out. Sorry, I forgot to update the instructions above to reflect the changes.

Just try this command: sudo apt-get install xulrunner-dev

That is, install xulrunner-dev and you should be able to compile the xpi.
install success but still not work, also i have installed xpi nu FF, global menu works for every application except fireafox
