Since my last Chrome update to 62, the HTML5 notifications don't work anymore (clicking on the enable notifications buttons does nothing).
In the browser's developper tools' console, the following message shows up:
[Deprecation] The Notification API may no longer be used from insecure origins. You should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
This seems to be part of a vast Google plan to reduce the capabilites over HTTP :
Once Chrome 62 hits the stable branch, there will be a flood of complaints. Maybe make an annoucement or propose a workaround?
