How to hide FirefoxDriver (using Selenium) without findElement function error in PhantomDriver(headless browser)?

Question

I try to make hidden FirefoxDriver. According to my research I must use PhantomJSDriver but when I use PhantomJSDriver driver.FindElement statement no longer does not work.<

Answer 1

Since version 55+ for Linux and 56+ for Windows & OSX, Firefox supports the -headless command line option. It shall be used like this:

o = selenium.webdriver.FirefoxOptions()
o.set_headless()
driver=selenium.webdriver.Firefox(options=o)

The corresponding code in C# would be:

var o = new FirefoxOptions()
o.AddArgument('-headless')
var driver = new FirefoxDriver(o)

Because the .NET wrapper doesn't support the .headless property.
