Mozilla is developing a push notification system for the Firefox Web browser. It will allow users to receive notifications from websites without having to keep those sites open in their browser.

For example, Redbox’s first push notification generated 16 times more traffic on its site than its busiest day of the year, the report says.

Apple Vision Pro users may not see many notifications while wearing the headset, with the discovery that visionOS doesn't natively support Progressive Web Apps and Web Push Notifications.

In that way, push notifications may indeed be the smartphone’s defining feature. They are, if nothing else, a perfect avatar of how frustrating it can be to own one.

Web Push, a multi-standard notification service for time-sensitive and high-priority events will be available for Safari 16 on macOS Ventura in October.
