I'm trying to use the Beacon API (https://developer.mozilla.org/en-US/docs/Web/API/Beacon_API), but Firefox (13.1) on iPhone X (iOS 11.4.1) will not communicate with a secure site (https). E.g.

navigator.sendBeacon('http://xxxx.com', 'data'); will send a POST but navigator.sendBeacon('https://xxxx.com', 'data'); will NOT send a POST.

navigator.sendBeacon() returns true on both secure (https) and insecure (http) sites.

macOS Firefox and iPhone Safari work fine. I've contacted Apple and they say it's a Firefox issue.

Chromium have investigated this and it is a WebKit issue. See comment for detailed explanation - https://bugs.chromium.org/p/chromium/issues/detail?id=878562#c17
