My goal is to send Gmail-style desktop notifications in Chrome or Firefox from a web app (let's call it X) that is NOT currently open in the browser, without requiring the user to install an app or extension. It's okay if the user needs to grant permission to receive notifications from X, and it's okay if the browser needs to be open for the notification to appear, as long as X doesn't need to be open in the browser. A solution that doesn't require any browser window to be open would also work.
I just spent the day digging into this, and so far I think I've learned:
I could be wrong about any of my statements above - I'd love to hear it! - and I'm open to any other solution too. Any ideas?
Thanks for reading.

This means the browser can have no windows open, and you'll still receive the push message in your service worker, because the browser in running in the background. The only time a push won't be received is when the browser is completely closed, i.e. not running at all (no marking).
Chrome, Firefox, Opera and Safari currently support web push notifications. Supported browsers vary by vendor. Notifications vary in appearance between browsers and operating systems. Some notifications use native notification centers, others don't.
You can send push notifications even when your web page is not active using Service Workers, the Notification API for service workers and the push API for server-initiated notifications (or scheduled notifications).
As of June 2016, Service Workers are supported in Chrome, Firefox and Opera. See the status at https://jakearchibald.github.io/isserviceworkerready/
