Firefox alert box not detected with Selenium WebDriver

ERROR net.serenitybdd.core.Serenity - No alert is present (WARNING: The server did not provide any stacktrace information)

I get this erro

Answer 1

A little more elegant solution :

WebDriverWait wait = new WebDriverWait(driver, timeout);
wait.until(ExpectedConditions.alertIsPresent());

Use the WebDriverWait, every time you have dynamic element that are not present when the page is done loading, like alert, popupwindow, modal popup, hiden element which turn visible,.
