With notifications, the complete mess for the browser Firefox (PC) also continues. Every day, the notification settings fly off spontaneously, I do not do anything and do not touch the settings at all.
For the Chromium (PC) browser, as it was once set up a long time ago, everything works fine.
Understand finally with notifications for Firefox (PC), though it’s already every day to reconnect all notifications.
The problem has lasted for more than two months !!
You wrote that in the course of this problem, but so far the improvements have not appeared.
