Create a special user to run Firefox

I'm trying to run Firefox as another user, following this tutorial: http://hack.org/mc/writings/firefox-another-user.html -- the script does su -l to the dedicated Firefox user, mcff:
Code:
su -l mcff /home/mcff/bin/fireweb $DISPLAY
I don't know how to create the dedicated Firefox user, I tried adduser and chose no password, but it still asks for password when I try su -l mcff .

Thanks
 
I'm assuming when you created the new user, you left the password field blank. In that case, I think a password would still technically exist, it would just be blank. I would think hitting the Enter key at the password prompt should work in this case.
