All I want is to be able to keep the prying eyes of my children from reading my favorites by downloading them onto a disk.Thanks, them

First, Favorites are specific to the user. So if you have a password protected user account, the kids won't see YOUR favorites.

However, if you want to save them this is the way I would do it. Create an HTML document on the disk for any favorite you don't want the kids to see. Then just add each URL. If you have MS Word, you can maintain this document in Word, just copy and paste each URL onto a separate line. When you open that doc in Word, you will have clickable links.
