如何使用NodeJS和Selenium在私有模式下启动Firefox？

Question

我正在尝试使用TypeScript在私有模式下启动Firefox。我已经尝试过了，它不会使用私有模式：

static async CreateFirefoxDriver():Promise<WebDriver>
{
    //Create the firefox capabilities
    var firefoxCapabilities = Capabilities.firefox();

    //Use Private Window
    var firefoxOptions = {
        'args': ['-private']};

    firefoxCapabilities.set('firefoxOptions', firefoxOptions);
    var driver = await new Builder().withCapabilities(firefoxCapabilities).build();

    //Maximize the window
    await driver.manage().window().maximize();
    return driver;
}

Answer 1

static async CreateFirefoxDriver():Promise<WebDriver>
{
    var options = new firefox.Options();
    options.addArguments("-private");

    var driver = await new Builder().forBrowser("firefox").setFirefoxOptions(options).build();

    //Maximize the window
    await driver.manage().window().maximize();
    return driver;
}
