Facebook Messenger is one of the most popular instant messaging apps today. People use it to stay in touch with family and friends every day.

The problem with using IM apps in the default light mode is that it can be hard on the eyes, especially in a dark room. One solution to this is Facebook Messenger in dark mode.

When you enable Facebook Messenger Dark mode, the entire background of the chat window changes to dark black. The other elements in the chat also change slightly.

If you don't like dark mode, you can just as easily switch back to light mode.
