Meteor/React client app works in Chrome, Safari but not in Firefox

Hi all,

I decided to put on my training wheels and learn react. I had written a simple Java applet a long time ago to learn Java when it first arrived, so thought that porting it might be a good start.

Maybe double check that you aren’t using an event reference somewhere without first passing it into the enclosing function. It’s possible Safari/Chrome are being more lenient with this (if they’re able to infer the event reference).
