I&#x27;ve been using Push Notifications on my site for a few months now [0]. Having gone through the detail on this announcement, I&#x27;m a bit confused and would like some clarity.<p>In Chrome &amp; Chrome for Android, I have to use GCM to let the device know that there&#x27;s a new message. The service worker then pings the server to find what the notifications are, before displaying them. Firefox supports sending payloads.<p>How can I distinguish between endpoints registered from FF, so I can send payloads directly without going via GCM?<p>Thanks<p>[0] <a href="https:&#x2F;&#x2F;movinggauteng.co.za" rel="nofollow">https:&#x2F;&#x2F;movinggauteng.co.za</a>. Users need to log in via social media, and then grant permissions for notifications by clicking on the crossed out bell at the top of the page.
