How do you open firefox incognito using selenium webdriver plugin?

[Jun Yi Lay]

I do not know how to open an incognito firefox window using selenium webdriver plugin under javascript. Does anyone know how to?

[Dmitri Tikhanski]

There is no way of doing this using WebDriver Sampler 3.3 as the Firefox initialization is happening within Firefox Driver Config so you will either have to patch this class to add -private argument like:

   DesiredCapabilities caps = new DesiredCapabilities();
   FirefoxOptions options = new FirefoxOptions();
   options.addArguments("-private");

   caps.setCapability("moz:firefoxOptions",options);

or consider switching to JSR223 Sampler where you will have full control over browser initialization and configuration

Do you mean adding the -private argument in the webdriver sampler script?
