For latest Firefox 53 or any newer firefox version sendkeys will fail when we open a browser/driver, because we are using older version of selenium, geckodriver & guava. Please upgrade your POM.xml: selenium 3.7.1 geckodriver to 0.19.1 guava 21.0 Download new geckodriver 0.19.1 version from here , you will see download links for different platforms/OS. Once you update all these, clean your project on eclipse & also better update maven for your project.
