As we all know that Firefox 57 will rename to Firefox Quantum. It means the New version Firefox will use Quantum Engine instead the old one.

Even throgh Firefox 57 is still in beta,but we can install it from PPA under Ubuntu.

sudo add-apt-repository ppa:mozillateam/firefox-next
sudo apt-get update
sudo apt-get install firefox

So here it is.
