No internet in the Firefox after installing Fedora 20

This is mostly because of the default IPV6 DNS enables of  the Firefox.
So you have to disable this if your service provider does not support IPV6 DNS.

1. Open Firefox and  type about:config in the address bar.

2. Press the [ I will be careful, I, Promise ]  button.

3. Type Network.dns in the search text box.

4. You will see network.dns.disableIPv6 entry in the searched list.

5. Double click on the above entry to change value column to True.

6. Restart the Firefox.

7. Now your internet is ready.
