"the push service application is no longer available. it may have been uninstalled. please re-enable unifiedpush to select a new service" but... I don't have UnifiedPush in Settings (anymore) nor in Secret Settings, was it removed? I can toggle off this notification channel as a fix for now touching the notification does nothing HOW TO HIDE IT FOR NOW: you can hide it, in Android Settings Notifications Fennec, or Fennec Settings Notifications, you'll end up in the same place or long-press on the notification and Turn off (depends on Android version etc) /LE: added "hide" section above
