not a regression

While the site is toggled to HTTP, the notifications do not launch in Chrome and Firefox. There are no warnings on the site about this so it's easy to accidentally conclude that notifications aren't working if you didn't know that this was expected behavior.

I'd like to see some text on the site letting users know about the expected behavior just to make testing easier.
