And after looking at past bugs, I don't know why we've switched between http/https for external resources depending on whether or not Koha was on https. Since they're external resources, there really is no harm in just using HTTPS all the time.
All dependent bugs are marked fixed, so I think this bug is ready to be closed.
Reopened to include Bug 21094
