Important: #83971 - Browser Notification API only works on SSL encrypted connections

See forge#83971

Description

Google Chrome has deprecated the JavaScript Notification API for unencrypted connections, which triggers warnings. Due to this TYPO3 does not use the LoginRefresh notification here anymore.

See https://goo.gl/rStTGz for more details.

Impact

The browser notifications for expired login only works on HTTPS.

Affected Installations

Any installation which does not use HTTPS.

Migration

Use SSL / HTTPS for the installation and the Notification API will work just like before.
