Error message in FF:
Server not found
Firefox can't find the server at forums.linuxmint.com.

ww.example.com instead of www.example.com
If you are unable to load any pages, check your computer's network
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.Error message in Chromium:
This webpage is not available
The server at www.google.co.in can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chromefrom accessing the network.
Here are some suggestions:
Reload this webpage later.
Check your Internet connection. Restart any router, modem, or other network devices you may be using.
Check your DNS settings. Contact your network administrator if you're not sure what this means.
Try disabling network prediction by following these steps: Go to the wrench menu > Settings > Show advanced settings... and deselect "Predict network actions to improve page load performance." If this does not resolve the issue, we recommend selecting this option again for improved performance.
Add Google Chrome as a permitted program in your firewall's or antivirus software's settings. If it is already a permitted program, try deleting it from the list of permitted programs and adding it again.
If you use a proxy server, check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server, adjust your proxy settings: Go to the wrench menu > Settings > Show advanced settings... > Change proxy settings... and make sure your configuration is set to "no proxy" or "direct."
Error 105 (net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's DNS address.
