Although Facebook is used every day of the week to upload photos and send millions of chat messages through the website and the company's various mobile apps for different platforms, there are still things that users simply don't like about the service which Facebook offers. Although it isn't brand new, one feature that seems to irk a lot of people is the read receipt status indicator that appears in Facebook Messages that shows when a message has been read, or otherwise commonly known as “seen”. If that bothers you, then it's now possible to install a simple browser extension to disable the feature when using Facebook chat through the website.
