I am using facebook from last 5 years. I’ve changed the device and was using facebook in google chrome. And when I tried to send the message to my friend it requires the facebook messanger. It means if I have to talk to my friend is it neccessary to have facebook messanger in the mobile? What the hell is this. Do you mean we can’t use facebook directly from google chrome or any other browser. To send a message to my friend first I have to install a 45 mb messanger for android and then wait because it took 3 to 4 minutes for installation. Why is it too slow? The app downloaded in just 3 to 4 minutes and taking too much time just for installing. This is pathetic. Facebook improve your apps. Otherwise there are some other applications available which are better than yours.
