Missing Bookmarks...again!

Hello Chummy, Chum, Chums... :)...!
It's happened again...
...all my Mozilla Firefox Bookmarks have disappeared...as always happens... >:(...!
I've located my backups in the usual way...as you do...
Mozilla > Firefox > Profiles > Bookmark Backups >.
and there are 5 of them, numbered 12, 13, 14, 15, and 16 (the latest) .HTML files.
The one I want to restore is number 15, the previous one....
So, Chums...
What do I do with number 15 HTML file to get it to list my old Bookmarks again...
...!
I've been through this bleedin' rigmarole before in the past, (dont we all?), but its always so bleedin' complicated in Firefox....
...., that I've forgotten how I did it last time!....
...!
What is the procedure, now that I have located the HTML File I wish to restore?....
...!
A Chocolate Cookie for the first Chum to describe the "simplest", "step by step", "easy-peasy", way of achieving it....
...!
Paul...Confucius is my middle name...trust me!...
...!
...got to keep laughing when all else fails!...
