If the full web link is in each address, try this;

Open the file in a word type program. It may change the addresses into usable links.

If not, mouse to the end of each link and press <Enter>. That should change it into a link.

Now save the file as an HTML file. All done. Now you can use the HTML in Firefox.

When I tried to open one in Word or notepad, it appeared as script. it does not look like it does in the favorites folder itself.

Don't use Wordpad, use Word.

What is the format of the file you are working from? Test only, or something else? Please open the file and take a snapshot so we can see it. Also, what is the full filename?

Here is the image of the file I want to use. There are number of favorites in sub folders as you can see.

That is not a file, that is a directory.

So therefore the favorites in this directory cannot be used? I can click on one and it will open in Firefox as the default browser. I guess I will have to use these from here and save them as I go. Is there any other way that you could see me importing these?

Aha, thanks for the screen shot, those are Windows Favorites. If you open Internet Explorer and check the Favorites list, is it using that folder or are those not yet restored into the current Windows Favorites folder?

The easiest thing to do next would be:

(1) If necessary, add the restored favorites to current the Windows Favorites folder

(2) Instruct Firefox to import bookmarks from Internet Explorer (see: Import Bookmarks and other data from Microsoft Edge)
