Html 5 push notifications stopped working for firefox

1

Hello,

I use html push notifications but for a while now it stopped working in Firefox.
from this test site I get messages
https://www.bennish.net/web-notifications.html
first I thought it was the permissions, but all is ok.
In Edge I do retrieve the notifications. but not in FF.

there is no error.
Is there something I can check. Permissions are allowed and I reregistered my browser but nothing seems to work.
My config is like this

  - platform: html5
    name: html5
    vapid_pub_key: Key
    vapid_prv_key: -Key
    vapid_email: email

Mine stopped working as well, but work from that website. Firefox is authorized, but it doesn’t show a notification. No error, nothing.

I don’t have a fix.
Only as workaround for push notifications I use edge now.
