WebDriverException: Message: Missing 'marionetteProtocol' field in handshake

问题

I'm currently trying to run a robotframework test scripts locally (Ubuntu 12.04 LTS 64 bit). The issue that I faced was not able to launch FF browser in Open Browser. Below is the details/specs of the setup that I have.

Firefox (v26.0)
Selenium2Library
selenium-server-standalone-2.53.1.jar
geckodriver-v0.9.0

Please note that I used same machine as hub and node (selenium grid)

Here the command to launch my hub :

java -jar selenium-server-standalone-2.53.1.jar -role hub -port 4444

While here's the command to register my node :

java -jar selenium-server-standalone-2.53.1.jar -role node -hub http://localhost:4444/grid/register -trustAllSSLCertificates

I did what is per told in https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver (add wires executable in the PATH)

I also did :

${ff default caps}    Evaluate    sys.modules['selenium.webdriver'].common.desired_capabilities.DesiredCapabilities.FIREFOX    sys,selenium.webdriver
Set To Dictionary    ${ff default caps}    marionette=${True}
Create Webdriver    Firefox    executable_path=\home\my\wires
Open Browser   ${HOMEPAGE}  ff  None  ${HUB}

As a result, the FF browser launch, but not opening the URL ${HOMEPAGE}. I've been googling around and stuck in this issue for so long. Please help..
