I struggled with registering my new Sophos XG home firewall for about 3 days thinking I had borked up the install somehow, but after re-installing from scratch after learning a few more of the 'sophos' nuances, I still couldn't register it, it just would sit there on the same registration screen until I skipped it. Then finally I tried IE and presto, it worked fine. Just thought I would pass that on to others who are getting tired of bumping their heads into the wall.
