Messenger Darkmode is a browser add-on developed by Maël Jallais that brings a dark mode experience to Facebook Messenger. This add-on is specifically designed to adapt to the user's system preferences, allowing for a seamless and user-friendly dark mode experience.

With Messenger Darkmode, users can enjoy a visually pleasing and comfortable browsing experience, especially in low-light environments. By syncing with the user's system preferences, the add-on automatically activates and deactivates the dark mode based on the system's settings. This means that users don't have to manually toggle the dark mode on and off every time they use Messenger.

The add-on seamlessly integrates into the Chrome browser, making it easy to install and use. It is completely free of charge, making it accessible to all users. Whether you prefer a light or dark mode, Messenger Darkmode ensures that your Messenger experience is in line with your system preferences, providing a visually appealing and personalized interface.
