Temat: Problem z sesjami i webdriverem

Po zalogowaniu się, webdriver nie trzyma sesji użytkownika. Oto kod:
WebDriver driver = new FirefoxDriver();
driver.get("https://snapsation.com/login");
WebElement email = driver.findElement(By.name(webElements.get(1)));
email.sendKeys("");
WebElement password = driver.findElement(By.name(webElements.get(2)));
password.sendKeys("");
email.submit();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
WebElement offers = driver.findElement(By.xpath("//div[@id='mainmenu']/div/div/a[4]/span/span"));
offers.click();
driver.manage().getCookies();
WebElement title = driver.findElement(By.name(webElements.get(0)));
title.sendKeys(codeInjection.get(startSize));
title.submit();

O co chodzi i dlaczego tak się dzieje?
