Finally i got it fixed after lot of struggle. It was happening because my localhost was mapped according to new Ipv6 standard like [::1] but the selenium needed the ipv4 address like 127.0.0.1. so i had to change it using the command in my system like this :

Open a terminal window and type this line:

sudo open -a TextEdit /etc/hosts

You will be prompt to type in your admin password and your host file will open in TextEdit. Add this line in your host file :

127.0.0.1 localhost

Save the file and close. That's it.

(addendum: TextEdit refused to save the file for me, even as superuser, so I used sudo vim /etc/hosts instead)
