If he is having problems with reaching some websites and not others it 
is a IPV6 DNS problem in Firefox ,
1. Do a about:config in Firefox URL and where it says "filter" at top 
put this line  "network.dns.disableIPv6   user set  boolean  true"
W/O quotes.

And double check down in body that it is entered correctly.


2.  In /etc make a file dhclient-eth0.conf and put in line,
"prepend domain-name-servers 127.0.0.1; "
W/o quotes

If you have a eth1 or wlan0 , you will have to make a file for them, 
just change the eth0 to eth1, wlan0, Etc.
