Also, on the Notifications settings page itself, I see this:
"The following websites have requested to send you notifications."
[Note: it is blank - there are none, but you could disallow any that are listed]
And at the bottom there's a checkbox (which is unchecked)
"Block new requests asking to allow notifications."
So, as the saying goes, "Something's not right."
Messages are the sole opinion of the author, especially the fishy ones.
