I’d like to try to reproduce the problem. I did a basic account creation test on OS X Mavericks, Firefox 33.0 and didn’t see a problem. Could you let me know your operating system version and browser version?
I’m seeing the same error when trying to install on 12.3.
$ sudo zypper in docker

Problem: nothing provides kernel >= 3.8.0 needed by docker-1.3.1-27.1.x86_64
Solution 1: do not install docker-1.3.1-27.1.x86_64
Solution 2: break docker-1.3.1-27.1.x86_64 by ignoring some of its dependencies
