When I try to open these files I get an error because .jsonlz4 is not a recognized file type for Adobe Acrobat. (Imagine that!) I have attached the entire error as an image. This issue occurred when I did a Refresh of Firefox.

You can only restore a compressed bookmarks.jsonlz4 file in the Firefox Bookmarks Manager (Library).

Thank you cor-el - it seems clear I got lost in the lengthy instructions and you pointed me to the correct path.
