I'm using chromium (a chrome build) under Arch linux at home.
Here are the console messages, first is likely the not-scripts blocking java.com; but it used to work when I re-enabled it. I think it may be trying to inspect the 'state' properly and not having a try/catch around it.
Also, when I 'copy' out a design it seems to forget the reactorplanner.html portion of the link.
