Facebook is testing a new feature within its Messenger instant messaging service that gives its users the opportunity to “react” to incoming messages, including the first time a Dislike option has appeared on any of Facebook’s services.

Here’s how you can replace Facebook’s boring Reactions emoji for something more eye catching, like Donald Trump pulling an array of strange faces, or perhaps something a little more Pokemon related.

The world’s largest social network Facebook has confirmed that a new feature called “Reactions” is officially being put through test in order to see how users interact with it. Users of Facebook have long wanted a “Dislike” button to be made available on the social network. After all, it seems a little unfair that you can “Like” a post, status update, photo, or comment, but you have no real way of showing dissatisfaction. Rather than integrating a “Dislike” button, Mark Zuckerberg has opted for a more dynamic feature that provides additional options to the end-user.
