Push notifications.

Push notifications for YouTube appeared before but I never clicked accept or deny. YouTube does not show up in my notification preferences and the popup to accept or deny does not appear when I visit YouTube, signed in or not.

How do I have Youtube (and maybe other sites) show the popup again?

Apparently the option only appears in Chrome in YouTube's notifications icon on its website. Sort of solved.
