You need to download latest geckodriver from here and Looking at the examples at this

It seems like you need to do is set marionette to true in the desiered capabilities as below :-

$capabilities->setCapability('marionette', true);

Example:

$host = 'http://localhost:4444/wd/hub';
$capabilities = DesiredCapabilities::firefox();
$capabilities->setCapability('marionette', true);
$driver = RemoteWebDriver::create($host, $capabilities, 5000);
