因此，我正在尝试Selenium自动化，并且试图编写一个测试用例，该用例可以登录，转到特定页面，输入数据，然后按Submit。问题在于，它运行时会键入凭据，然后按“提交”，网站将返回：

该站点使用HTTP cookie来验证授权信息。请启用HTTP cookie以继续。

但是，当我添加此行[以// 1表示]时：

driver.findElement(By.cssSelector("p > input[type=\"submit\"]")).click();

它允许登录通过，直到到达发送消息页面[以//
2表示]，然后再次要求提供凭据（就像从未登录过一样）。那么，Firefox根本不接受Cookie吗？我该如何解决？
