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 Byconfirmation 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.

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).

• If you are using Adblock Plus on Firefox, click on the AdBlockPlus icon and go to Filter Preferences > Custom Filters. Click on Add Filter Group and use any name for it. Now click on Actions > Show/hide filters > Add Filter, and add this in it,

Note that its a good idea to use a meaningful name for the filter so that you remember its purpose in future. I have named it, Disable Facebook Chat Receipt.

• If you are using Adblock Plus on Google Chrome, open chrome://extensions and click on Options for Adblock Plus. Then go to Add your own Filter > Add Fiter and paste the following code into it,

Click on Add Filter to confirm.
