Yes that is correct. If I click on the address bar and press space, then I can see the top sites which were present in v77.x.
Sadly something has change in v78.x, resulting in only 7 top sites now being shown below the address bar.
So, Top Sites is the only thing that you can show when the urlbar is empty or contains the current page uri. If you disable Top Sites in about:preferences you won't see anything.
These Top Sites used to be limited at 8 or less, and they can be fully customized in the New Tab Page or, if you unpin all the sites, they will update automatically based on visits/bookmarks.
In Firefox 79 we fixed bug 1631848, that allows Top Sites to respect maxRichResults, provided those pages are also visible in the New Tab Page (This is to avoid confusing users about where additional rows came from).
Thus, from Firefox 79 if you want to see maxRichResults Top Sites you will just enable 3 Top Sites rows in about:preferences#home. You can also hide or disable Top Sites in the New Tab Page if you don't want them there, the only thing that matters is that you set Top Sites to 3 rows.
For now that's what we have, one day it will be possible to manage Top Sites directly from the urlbar and then we'll be able to drop these connections with the New Tab Page.
I'm duping to bug 1631848, because that's the current solution we can provide to this problem, we'll do better in the future with upcoming changes.

I'm not entirely sure I understand, perhaps you haven't explained enough or I haven't been descriptive enough?
I am not talking about new tab pages. I am talking about the drop down "Top Sites" list in the address bar which appears when you the click on the address bar from any page, website or new tab.
I do not use the new tab page, therefore I am not talking about the new tab page and never have done.
Can you please provide me instructions that tell me how to display the top 15 sites again, when v77 of Firefox respected the browser.urlbar.maxRichResults setting? Perhaps your instructions above have already told me how, but it is not entirely obvious or clear.
