Like the title says. Stated getting this notification every time I open fennec.
The push service application is no longer available. It may have been uninstalled. Please re-inable UnifiedPush.
Is this something I should do or is there a way to turn this off?
Unified push is a way to get live notifications on your phone. Google provides Firebase Cloud Messaging to do this with Google Play Services and unified push offers an alternative. If you want to know more about the topic, you read more on https://unifiedpush.org/
