When you use Facebook chat to talk with someone, a Seen By confirmation is displayed in the your Facebook chat box once your friend on the opposite end has actually seen or read the message. The Facebook seen message also contains the exact time when your friend has seen the message.
Its a great feature as it confirms if your message on Facebook chat has been delivered. But its also a privacy issue. Sometimes, you may want to not want your friends’ to know that you have seen a Facebook chat message sent by them. But its impossible because as soon as you see the message, a Seen By confirmation will be displayed instantly in your friend’s Facebook chat box.
If you want to turn off ‘Seen By’ receipt feature in the Facebook chat, there is no official way to do this. Facebook privacy settings may include an option to turn off the ‘Seen By’ message in Facebook chat but for now you must use third party solution to hide it. Here’s a list of working solutions.
Check The Message Without Opening It
If you go to the Facebook’s messages page, you will notice that small messages sent by your friends are fully visible in the preview box.
If you read a message just from the preview and DO NOT click on the message, you have not actually ‘seen’ the message, and thus, Facebook will not send the ‘seen by’ confirmation message to your friend.
Unfortunately, this is only applicable to short messages. You will not be able to read long messages this way (for example, the first message in the screenshot).
