What's your jdk version?

Answer 1

I doubt that the JDK you are using is outdated. Kindly update your JDK to the latest version. It should resolve your error. For Selenium 3.0.1 you need minimum JDK version 1.8.

 

Hope that helps!

After analysis,figured out that FF v<50 is not supported with webdriver 3.0.1
