I can't enable push notifications - when I try, it displays this message. Refreshing the page does no good. I'm using Firefox on an Android phone.
EDIT: Notifications do actually work (I got one just now) and the setting is turned on in Firefox, but it still asks me to enable them.
Love the update, btw! Everything looks fresh and new, and I'm super happy about the new features. The site works much faster and smoother too.
