I have noticed over the updates the notification badges has disappeared. Is this something of a know issue and will be worked out?
For reference: https://didrocks.fr/2017/09/25/ubuntu-gnome-shell-in-artful-day-14/
I’m still seeing ‘badges’ for Thunderbird in both Ubuntu 18.04 and 20.04 (dev) but not for Firefox or Chromium.
There are several open bugs for these issues including:
It seems that integration between the desktop and Firefox/Thunderbird was better when Unity was the Ubuntu’s default desktop environment. I don’t remember seeing any such integration with the Chromium browser though.
They work very well for me in 18.04 for Thunderbird and telegram
Chrome only sometimes
And Firefox never indeed
