I made this little video if you could please watch it. It explains the situation.
In a nutshell, I fiddled with a setting on a notification pop up that I thought I could revert, but I can’t figure out a way to get the pop-ups to come back. The monitor is running, I just need these notifications to come back.
I am using an updated Firefox browser on windows ten. The only thing that changed is that I messed with the setting on one of the pop-ups to hide the pop-ups I thought that would be temporary, but I can’t figure out a way to get the pop-ups and the notification sound to come back.
