Does anyone else have the problem that firefox denies acces to `navigator.geolocation.getCurrentPosition` even if the user clicks "allow"? I hoped it was fixed in the release but seems to be not the case.
I tried https://developer.mozilla.org/en-US/docs/Web/API/Geolocation... in Firefox 66 on macOS and Windows. I got "Unable to retrieve your location" on macOS (though it worked in Chrome on macOS). It worked on Windows, though.
If disabling CoreLocation fixes the problem, you might look in macOS System Preferences for location permissions. The first time an application tries to use the local location service, macOS prompts the user to grant permission to the application. If you accidentally click "deny", then macOS will automatically deny all future Firefox location requests.
