Modern web browsers now limit functionality for sites that are not secure. Important features that improve the quality of the website now require HTTPS. Geolocation, push notifications and the service workers needed to run progressive web applications (PWAs) all require heightened security. This makes sense; data such as a user’s location is sensitive and can be used for nefarious purposes.
Please and thank you.
PS. I was using FF ver 84.0. About the older version
