Actually, your favorites just point to a file on the curezone server. If curezone ever goes out of business, the server won't be there, and neither will the file. When you click on your favorite link, the file will not be there, and you will get a "File not found" error.
So the safest thing is to cut and paste it into a file. Back up the file from time to time in case your hard drive crashes, after all it can't last forever. Then make an additional backup, and put it into a safe deposit box in case there's a fire. Then put additional copies into other safe deposit boxes in other parts of the country, in case a disaster strikes your geographic region. And after all floppies can't last forever, so make a printed copy. But just in case there's a fire...
