Meta will phase out its standalone Messenger applications for Windows and Mac computers, with functionality expected to cease around December 15, 2025. After this date, users will be redirected to Messenger.com or Facebook.com. Users are advised to back up their messages and media, and utilize secure storage features for a smooth transition to web-based Messenger or mobile applications. In 2024, Meta launched a Progressive Web App (PWA) version of Messenger, which operates within a browser and offers similar functionalities to the desktop applications. The Messenger desktop app has also been removed from the Mac App Store. Meta is enhancing its Threads app with new features, including private messaging, to compete with other platforms. The company faces lawsuits related to youth mental health concerns and has faced backlash for using user AI chat data for ad personalization without an opt-out option.
