我正在使用带有Ubuntu和Firefox浏览器的selenium web驱动程序（版本47）。在运行我的java脚本时，Firefox窗口出现并突然关闭。在控制台上，它显示以下异常。

我完全卸载了Firefox并再次安装它，但我仍然遇到这个问题。以前java脚本以下工作正常。但突然间它开始向我显示错误。 我的脚本如下 -
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.Test;
import eBastaTestingClasses.GenerateReport;
public class QuickBuy
{
@Test (priority = 1)
public void quickSearch()
{
try
{
WebDriver wd = new FirefoxDriver();
wd.get("http://14.139.112.73:8001/local-test/");
wd.findElement(By.xpath("//*[@id='edit-field-ebasta-name-value']")).sendKeys("test31march2016");
wd.findElement(By.xpath("//*[@id='edit-submit-quick-buy']")).click();
if (wd.getCurrentUrl() == "http://14.139.112.73:8001/local-test/")
{
System.out.println("Pass");
}
else
{
System.out.println("Fail");
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
有人能告诉我如何解决这个问题。相同的脚本适用于Chrome驱动程序。但是我想在Firefox中解决这个问题。
