Solution 1

this issue is solved with geckodriver 0.15 and selenium 3.3 version.

Solution 2

You need to download geckodriver. And then set

System.setProperty("webdriver.gecko.driver", "path\\to\\geckodriver.exe")

Check this link.

I am setting the System property but still getting the error, System.setProperty("webdriver.gecko.driver", "..<Path>../geckodriver.exe"); capabilities = DesiredCapabilities.firefox(); capabilities.setCapability("marionette", true); driver = new FirefoxDriver(capabilities);

How are you writing the path to the geckodriver.exe?

[Immers Cherub]

The path format should be "D:\\work\\project\\geckodriver.exe". It will not work if you just set the path as you just wrote above.

This made me realize that for geckodriver 0.17 you need Selenium 3.4.0

I still have the same problem with geckodriver 0.20.1 and Selenium 3.11.0. Here is my question: stackoverflow.com/questions/49969902/…
