Just guessing, as I don't use Firefox under profiles, but it seems this should work.
Open Firefox with the profile that has the Bookmarks you want. Click Bookmarks, Export, and export the html file to your desktop. Close that Firefox profile.
Open Firefox under the New profile, Click File Import, and import the html file you just saved to your desktop to the new profile.
If you're only wanting to export 1 or 2 Folders, I'm not sure that can be done. I just poked around for a few minutes, tried Cut/Paste, Copy/Paste, etc. It doesn't appear you can export only 1 or 2 folders.
