Automated tests fail on Firefox Windows

[Ross]

Environment

adblockpluschrome / master / 2207:96eda29ae585

How to reproduce

1. Run npm test on Windows.

Observed behaviour

Following on from #7166. If I manually add the webdriver binaries to my PATH env, Chrome works fine.

However Firefox/Gecko fails with the following when ran against the current live version of testpages.adblockplus.org:

AssertionError [ERR_ASSERTION]: Element Hiding - Class Selector
+ expected - actual

-false
+true

at takeScreenshot.then.screenshot (test\wrappers\pages.js:240:22)

And fails with the following when run against a locally running version of the test pages:

NoSuchFrameError: Unable to locate frame: undefined
      at Object.throwDecodedError (node_modules\selenium-webdriver\lib\error.js:514:15)
      at parseHttpResponse (node_modules\selenium-webdriver\lib\http.js:519:13)
      at doSend.then.response (node_modules\selenium-webdriver\lib\http.js:441:30)
      at <anonymous>
      at process._tickCallback (internal/process/next_tick.js:188:7)
  From: Task: WebDriver.switchTo().frame(0)
      at thenableWebDriverProxy.schedule (node_modules\selenium-webdriver\lib\webdriver.js:807:17)
      at TargetLocator.frame (node_modules\selenium-webdriver\lib\webdriver.js:1824:25)
      at closeWindow (test\wrappers\pages.js:61:25)
      at resolve (test\wrappers\pages.js:43:52)
      at new Promise (<anonymous>)
      at driver.switchTo.window.then (test\wrappers\pages.js:43:9)

Expected behaviour

The automated tests to run in Firefox succesfully.
