Facebook lets you know when someone has “seen” your message, but a Chrome extension called FseenBlock keeps you hidden from life’s annoyances.
The extension blocks the functionality that lets others know when you saw a message, and you can also disable Facebook Chat from showing you are typing.
Once you feel like letting someone know you have seen their message, you can click on a blue checkmark within the Chat window.
FseenBlock works inside both Chat windows and your Messages inbox, and even if you happen to refresh the page, it still works as advertised.
While the Chrome extension only has around 1,200 users, it does have a five star rating.
To see it in action, and start hiding from your annoying Facebook friends, you can check out the video below.
