getWindowHandles（）在Firefox 58中不起作用。焦点停留在父选项卡上，并且不会转移到下一个选项卡

getWindowHandles()

getWindowHandles()

System.setProperty("webdriver.gecko.driver", "C:\Utility\BrowserDrivers\geckodriver.exe");WebDriver driver= new FirefoxDriver();driver.get("https://www.facebook.com/");String parent= driver.getWindowHandle();System.out.println("Parent Window is"+parent);driver.findElement(By.linkText("Data Policy")).click();WebDriverWait wait = new WebDriverWait(driver,5);wait.until(ExpectedConditions.numberOfWindowsToBe(2));Set<String> s1= driver.getWindowHandles();for(String s2:s1){    if(!parent.equalsIgnoreCase(s2))        { driver.switchTo().window(s2); Thread.sleep(5000); System.out.println(driver.getWindowHandle()); System.out.println("get title of window"+driver.getTitle());        }}

控制台输出：

Parent Window is42949672974294967303get title of windowData Policy
