How to Maximize a firefox browser window using Selenium WebDriver with node.js

How do we maximize a firefox browser using Selenium WebDriver (Selenium 2) with node.js. I am using wd package for Selenium WebDriver to write the tests. I have tried executing window.resizeTo(1366,768); inside a 'eval' or 'execute' but didn't work. Please advice.

I am using Selenium WebDriver 2.25.0

Have you tried : 

driver.manage().window().maximize()

Doc

First instantiate a firefox driver

WebDriver driver = new FirefoxDriver();

then maximize it

 driver.manage().window().maximize();

Using driver.manage().window().maximize() works well, Please make sure that you give enough time for the window to load before you declare this statement. If you are finding any element to input some data then provide reasonable delay between this and the input statement.

If you are using Selenium WebdriverJS than the below code should work:

var window = new webdriver.WebDriver.Window(driver);
window.maximize();

Call window as a function.

driver.manage().window().maximize();

Try this working for Firefox:

driver.manage().window.maximize();

The statement :: driver.manage().window.maximize(); Works perfectly, but the window maximizes only after loading the page on browser, it does not maximizes at the time of initializing the browser.

here : (driver) is called object of Firefox driver, it may be any thing depending on the initializing of Firefox object by you only. 

driver.Manage().Window.Maximize();
