you need to change this to `process.env.TRAVIS ? 'Firefox' : 'Chrome'`, it's lame I know - it used to be set from the grunt task, but I need the "sauce" e2e test to use "sl_chrome" browser...

This whole e2e testing story is horrible, @Dignifiedquire is already working on a little e2e testing framework that will allow us much better testing. Once I get 0.10 out, I will make this the highest priority.
