Disable very annoying push notification permission dialogs?!

Recently on zoho wiki pages, on every single page load an annoying Push Notification permission dialog pops up. In different browsers it does different things.

In Firefox it pops up at top left and stays there until dismissed, requiring the puzzled user to make some decision that they neither understand nor care about.

In Chrome (and on Mac not sure what browser), it flashes up briefly, and before you can read and click it, it disappears.

My request -- how do I, or you, stop users from being bombarded, as I say on every page, with this annoyance?

And, what are these "notifications" anyway? What form would they arrive in? Email? Random popups in the browser? Flowers from FTD? :-)
