I am unable to visit most sites online in either firefox or chrome. I can access google docs so I am researching on windows 7 (dualboot) and rebooting into Ubuntu (recently upgraded to 16.04).
$ sudo /etc/init.d/dns-clean $

Test 5: Chrome
This site can’t be reached
www.reddit.com’s server DNS address could not be found.
Test 6: Firefox
Server not found
Firefox can’t find the server at www.reddit.com.
Check the address for typing errors such as ww.example.com instead of www.example.com
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Edit: Almost forgot, this seems to have started after I tried installing PlayOnLinux the other day. I uninstalled it but the problems persist.
Re: possible duplicate question : dns_probe_finished_nxdomain error caused by Ubuntu dns_probe_finished_nxdomain error caused by Ubuntu I clearly state in my question that the solution posed in the other thread of clearing the dns cache does not resolve my issue.
