Discreet Messenger is a Chrome browser extension developed by NullPException. It aims to enhance user privacy and provide a distraction-free experience by altering the appearance of the Facebook Messenger web UI. With Discreet Messenger, unnecessary elements such as images, icons, videos, call icons, and previews are hidden, giving you a cleaner interface.

One of the key features of Discreet Messenger is its focus on user privacy. It does not access or check any personal data, ensuring that your conversations remain confidential. The extension is also open-source and hosted on a public repository on GitHub, allowing users to review the code and contribute to its development.
