I like ntfy, i use it to mostly for transfer text from one device to another especially when i am working in a non owned device. It is easy to transfer text (for bookmark, quotes, notes) as i am already using #sunup i don't want another push notification distributer so i tried whether i can use ntfy as PWA app through #fennec browser as it use #unifiedpush to send notification. This setup worked great for me so far.

One problem is #fennec need to be foreground or background
