One of the major features of Refresh is removing your extensions. ([[Refresh Firefox - reset add-ons and settings]]) What problem led you to use Refresh? Extensions work in a wide range of ways. It is difficult to know exactly what you would need to copy from your old data to get the program AND all of its stored data (preferences, database entries, etc.). It often is easier to reinstall from the source and configure again. See also: [https://support.mozilla.org/questions/1173024 I did a Reset of Firefox - How do i get add my 'Old firefox data' back?]

Thanks for your help. After doing a little more research I was able to import the extensions from my back-up to the new profile.
