Additional Information -
Running NUnit Tests using Selenium Grid. Issue cannot reproduce with Firefox 46 or previous versions.
You will need to use the new Firefox driver from version 47 onwards. See https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver for details.
I'm using the Fx 47 build that will most likely be declared today as the official one (from here: https://ftp.mozilla.org/pub/firefox/releases/47.0/ ) - and still experiencing the issue here, so it seems the addon signing hasn't been pushed to 48...
The issue is that code to support cert override was changed in a way that broke Selenium which in turn then crashed Firefox. There is a fix in the works from Mozilla.
As a work around you can either revert to Firefox 46 or you can use Marionette*. We have documented how to get set up with Marionette on MDN.
* Set firefox to latest for travis as Selenium - Firefox issue is now fixed SeleniumHQ/selenium#2110. * Remove single quotes Travis did not install and run firebox test. This may correct it. * Change to firefox 47 Firefox 48 is not working with selenium, but Firefox 47.0.1 does work. Hopefully this will work instead of 46. See SeleniumHQ/selenium#2110 * Try firefox 47.0.1 Using firefox: latest or 47 travis Firefox tests don't run. Last try to see if 47.0.1 will work. Otherwise for now we should stick with `firefox: '46'. * Change Firefox to use latest instead of 46 Per WCT issue https://github.com/Polymer/web-component-tester/issues/367 this should work.
