Awesome post sir, now anyone can block Facebook on Computer. This post is really helpfull. This method is too long we can block Facebook by an Awesome software and can easily trust on it. We can get access to Facebook with proxy servers or vpn tricks if we use this or any other method to block any website. But if we use software which I'm talking about no one can open Facebook without your permission. You just have to download lock fb. Thank you..... :-)
