问题 Is there a way to remove a Web Push Notification once shown? To remove it from the notification list on the device - or mark it as "read"? I assume this can't be done from the server, and I've been hunting around for a Javascript API - but I haven't found anything. (The wider problem that I'm trying to crack is how to synchronise notifications on multiple screens/browsers/devices.) 回答1: I think might be impossible. As you can show and hide a notification. And this can be a workaround for

问题 According to the spec, a pushsubscriptionchange event indicates that "a push subscription has been invalidated, or will soon be invalidated." What are the best practices for handling this event? 回答1: Process the re-subscription entirely within the service worker.

问题 I am trying to set-up a Firebase-messaging-sw.js file (for web push notifications).

问题 I'm setting up Firebase Cloud Messaging to do push notifications on the web. It works but only with Chrome (Windows and Android) and Firefox(Android) so far. It's not working on Samsung Internet Browser (the browser that comes pre-installed on Samsung's phones) and I haven't gotten a chance to test on iOS so far.
