I have a problem with Push notifications only on Firefox. It always return 'denied' when I am checking the permissions, even though they are granted and firefox shows me next to url tab that they are granted.
I have this problem on production (https). I was looking for an answer online, but every time people had this problem on localhost. On chrome and safari it works fine. Have you ran on that issue and have a solution ?
PS. For example on old Firefox 79 it works perfectly fine.
