The list we had before was a list of the top frecent pages.
The NewTab page list is also based on that list, so their initial contents are very similar. The NewTab page list though is customizable, while the old one wasn't. That means you can pin and move around pages, you can remove pages, you can also have search shortcuts there.
In practice that means you can have a customizable version of the old list. If you remove any pinned pages from the NewTab page you should end up with the old list (modulo really minor differences).
We actually think the new list gives more value and customization.
Regarding the duplication, the list is not automatically opened in the NewTab page, exactly because it would duplicate contents, on the other side you can now use the Top Sites list from any other tab.

Side note: you can still reach the old list by typing a ^ symbol in the urlbar
First of all, thank you for taking the time to explain the old behavior and the reasoning behind the Top Sites in the address bar. Also, while I know the existence of the ^ operator, I didn't know using it would result in the original list.
Can you be more specific about why you don't like being able to customize the list to your preference, compared to having a carved in stone list of pages you can't change?
Same answer as Chris Midgley in comment #6: I was using the address bar and New Tab Page for different things. I have 18 sites pinned on the New Tab page. My unpinned history starts at position 19, so it won't ever appear in the address bar with its 10-ish results (unless I start typing and there is a match with my history).
So now in FF75, with the Top Sites in the address bar
... I loose the history dropdown which was complementary to my bookmarks/pinned sites (unless I unpin everything on the New Tab page, but what's the point of it then?)
... I win the Top Sites being at my disposal from any tab, like you mentioned.
I can live with the current situation (duplication + ^ operator), but I feel like having the option to choose the content of the dropdown could be advantageous for users who just open a new tab for accessing their pinned Top Sites, and thus want something complementary to appear by default in the address bar dropdown, like their page history. Probably a nice-to-have. Thanks again.
