We are also encountering this problem for Firefox 47: https://travis-ci.org/Polymer/polymer/builds/136000685#L1310

Since upgrading to Firefox 47 I can no longer run tests on my Mac. I get a gatekeeper error that firefox-bin has not been signed and therefore isn’t allowed to run. Selenium 2.53.0 installed and hasn’t changed so suspect this might be a Firefox issue.
