Because of the Flash concerns raised by Brian Krebs (see other thread) I set up another two profiles.
The first problem was with my Identity Safe but bjm & Yank resolved that here: https://community.norton.com/en/forums/can-i-export-my-identity-safe-data-another-profile-my-pc
The other problem is that I'd like my IE11 Favourites to be the same on all three profiles, if only on a snapshot basis (i.e. I'd need to update whenever I added a new Favourite).
I can't see a way to do this - is it possible?
