What is the file extension of that "backup" file?

HTML needs to be imported, and JSON has to be restored.

Bookmarks > Organize Bookmarks -> Import & Backup - Import HTML... or Restore

Make sure that the backup file with the bookmarks has the correct file extension: .html for a HTML backup and .json for a JSON backup.

You can check that via the right-click context menu of that file and open the Properties.
If you are not sure about the file type then you can open the file in Firefox via "File > Open File"
A JSON backup will show as one long text line without line breaks and a HTML backup as a web page with clickable links.

A JSON backup starts with: {"title":"","id":1,"dateAdded":
An HTML backup starts with: <!DOCTYPE NETSCAPE-Bookmark-file-1>

You may need to add quotes ("") around the name to rename the file to the correct file extension.

Yes, it is a json file and it is still unrecognized.
