I searched for some solutions and got the following snippet to handled the issue
我搜索了一些解决方案并得到了以下代码段来处理这个问题
//Now the alert appears. Alert alert = driver.switchTo().alert(); alert.accept();
//现在出现警报。警报 alert = driver.switchTo().alert(); 警报。接受（）；
It works fine , but the alert popup appears in different instances (or different scenarios ) for which the alert cannot be handled in all blocks of code
它工作正常，但警报弹出窗口出现在无法在所有代码块中处理警报的不同实例（或不同场景）中。
Please let me know if there is any common approach wherein i can disable this alert popup permanently through some firefox profile settings or anyother generic approaches
请让我知道是否有任何通用方法可以通过某些 Firefox 配置文件设置或任何其他通用方法永久禁用此警报弹出窗口
I am using Selenium Java with browser as Firefox
我在浏览器中使用 Selenium Java 作为 Firefox

Write a method like this:
写一个这样的方法：
protected boolean isAlertPresent() {
try {
driver.switchTo().alert();
return true;
} catch (NoAlertPresentException e) {
return false;
}
}
Call the above method to verify whether alert is present or not as below:
调用上面的方法来验证警报是否存在，如下所示：
if(isAlertPresent()){
System.out.println(isAlertPresent());
driver.switchTo().alert().accept();
}
