How to open a new tab using Selenium WebDriver?

Question

How to open a new tab in the existing Firefox browser using Selenium WebDriver (a.k.a. Selenium 2)?

Answer 1

To open new tab using JavascriptExecutor,

((JavascriptExecutor) driver).executeScript("window.open()");
ArrayList tabs = new ArrayList(driver.getWindowHandles());
driver.switchTo().window(tabs.get(1));

Will control on tab as according to index:

driver.switchTo().window(tabs.get(1));

Driver control on main tab:

driver.switchTo().window(tabs.get(0));
