Facebook read message alerts?

[highcattle839]

If I facebook email a person not on my friends list will I still be able to see when they read the message? I was able to see that notification before but now it doesn't seem to show up at the bottom of the message. can the other person disallow that notification to be sent?

Yes, the person can disallow to send that notification.

There is a small add-on/extension named "Chat Undetected" to restrict the sending of read time...!
