Americans spend more of their digital time on Facebook than just about anywhere else outside of YouTube. They spend a lot of this time chatting (and arguing) with other people, liking and loving their posts. But there’s one thing you still can’t do on Facebook: dislike a post, despite the fact that a thumbs-down “dislike” button is the most asked-for missing Facebook feature.

That hasn’t changed, really, but if a new test being conducted in Facebook Messenger is any indication, the “thumbs-down” emoji is finally on Facebook. While you can’t dislike someone’s post in the regular Facebook newsfeed, some users can now dislike a message in private chats on Facebook messenger.

Facebook confirmed the new feature to Techcrunch, saying, “We’re always testing ways to make Messenger more fun and engaging. This is a small test where we enable people to share an emoji that best represents their feelings on a message.”

To use it (and to see if you have the feature on your account), just open a chat and hover over a message. If you see the emojis, you’re in.

In other Facebook news, the fight against fake news continues as the social network has now started marking news stories that are reported by other users to be fake appear as “disputed.“ Once reported, Facebook fact checkers will take a look and mark it as disputed. They won’t remove it, however, which should thwart users who seek to abuse the fake-news reporting system just to further, say, a political narrative. You can even find out why a story was marked as disputed by hovering over it with your mouse pointer.

This feature is also rolling out to some users, so it may not show up on your account just yet.
