Okay another update/query.
I missed with the inspector, and changed the element class from hidden to blank, to make the Notifications providers appear again.
I’ve succesfully enabled notifications for Safari again (I had to click the button to connect rapidly though, one simple tap wasn’t enough) 
Liked my own comment to test it out.
But, my favorite browser is Firefox. I’m STILL unable to get it to work. Even on a private window. I’ve disabled extensions, enabled cross-browser tracking and cookies, accepted cookies.
I do get the question about whether I was Trakt to sent notifications, and I hit “allow” (“toestaan” in Dutch), but then it’s still not connected to Firefox.
Does this help anything for Web developers?
there’s no errors in the console related to onesignal either.
