Does not work in Firefox

[pbrisbin]

Steps:

• Firefox 37.0.1-2
• https://carnivalapp.io
• Hover, click "Leave comment"
• See in console:

InvalidAccessError: A parameter or an operation is not supported by the underlying object

Based this: http://stackoverflow.com/questions/16677893/evil-firefox-error-a-parameter-or-an-operation-is-not-supported-by-the-under, it's because of the async: false on the call for user information (see #170). One solution may be here: http://stackoverflow.com/questions/16668386/cors-synchronous-requests-not-working-in-firefox

Reopening, the fix was not a fix and breaks other browsers. We need to instead fix #170 to get things working in Firefox.

This seems to be working in Firefox now. I think this was fixed by #170.
