How to display newly added bookmarks on top of the list in Unsorted Bookmarks? (not in Bookmark Manager window)

Question

I have hundreds of bookmarks.The Bookmarks Toolbar is filled.I made a shortcut of the "Unsorted Bookmarks" folder and placed it in on the Bookmarks Toolbar.Whenever I click the star to add a bookmark, it adds one to the real Unsorted Bookmarks, which add a copy of that bookmarks into the folder named Unsorted Bookmarks which is on the Bookmarks Toolbar.
When I click on the Unsorted Bookmarks(both original and shortcut folder), it displays the oldest bookmarks on top, which honestly makes no sense to me because the user has to scroll a lot to get to the newest bookmarks, which are more likely to be used than the old ones that have been sitting there for a long time.Is there any way to sort the bookmarks by a reversed chronological order and display newly added ones on top of the list ?
I am aware that you can do this in Bookmarks Manager window(called Library?) but it requires too many steps and it's time consuming and not easy to use in general.I'd rather click on the folder on Bookmarks Toolbar to open my bookmarks, but they show old ones on top.
Thanks !

Hmm, you might need to create a "smart folder" for this. You may have noticed some blue folders in your bookmarks such as "Most Visited" and "Recently Bookmarked". These show the results of a query run against your bookmarks or history (Places database) and you can create your own queries with a little elbow grease.
So one possibility might be to create a custom "Recently Bookmarked" folder that extends beyond the current limit of 10. I gave the steps for creating a 20-item version of this folder in this post: https://support.mozilla.org/questions/934205#answer-358492
That example searched ''all'' bookmarks and not specifically Unsorted Bookmarks. To create a new "smart folder" for Unsorted Bookmarks, you could try this:
(1) Select and copy the following places search query:
place:queryType=1&folder=UNFILED_BOOKMARKS&folder=UNFILED_BOOKMARKS&sort=12&excludeQueries=1
''(For definitions of those parameters and many more, see: [https://developer.mozilla.org/docs/Places_query_URIs])''
(2) Expand the Bookmarks Menu (e.g., from the toolbar button or menu bar, or in the sidebar or Library dialog), right-click the first bookmark, and choose New Bookmark
(3) In the Location field, paste the query (Ctrl+v or right-click > Paste)
(4) In the Name, enter something like Unsorted Desc (for descending order) or the name of your choice. Then click Add.
(5) Drag the new bookmark to the desired location on the Bookmarks Toolbar. If you are using the menu, click and drag and hover over Bookmarks Toolbar until it expands. Once it is on the toolbar, you can easily move it again to the desired location. During the first move, Firefox will recognize it as a query-type bookmark so that is why I have you create it on the menu and move it to the toolbar.
