Extension summary

Tired of the default Facebook Messenger notification sound, wanting to close out of a chat you're not currently reading, or hoping to see your unread count at a quick glance? Messenger Web App Upgrades adds some new usability features to help:

  • Set a custom notification sound for new messages
  • Press the Escape key to close out of the current chat
  • Display unread badges (only if the site is installed as a PWA)

Install and launch the extension, configure settings as desired, then refresh Messenger for the changes to take effect.

Uploaded audio data is stored exclusively on-device. Additionally, the extension does not collect data or report back to any server or cloud service.
