This is very simple, the only thing you need to do is just download an extension for your respective Brower.

Steps To add Browser Extension to your Computers

You’ll have to Install Download FB Unseen extension.

Click on “Add To Chrome”.

If you are new in Chrome a pop-up window will appear after you click on “Add To Chrome”, simply click on “Install” button and after few seconds your extension is ready.

Once you have installed FB Unseen extension to your chrome browser, your friends or conversational partners will no longer be able to see whether you have read messages sent by them or not.
