Selenium webdriver 无法从Selenium Webdriver版本3.4.0启动Firefox浏览器

我面临一个问题，即我无法从64位Windows操作系统（Windows 7）上启动Selenium Webdriver 3.4.0版firefox。 目前，firefox版本52.0.2安装在我的机器上。 我还向库中添加了SeleniumJAR文件，但它仍然显示错误

我的代码：

package sanity;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Login
{
        public static void main(String[] args)    
        {
            WebDriver driver=new FirefoxDriver();    
            driver.close(); 
        }
}

请使用“驱动程序.退出”而不是“驱动程序.关闭”重试

关于“Javascript错误（AddonManager）”，我还在想办法解决它，如果有人知道解决方法，请与我们分享：）

你的Firefox版本是什么

有时问题是安装的FireFox版本和geckodriver版本之间的不兼容

关于“Javascript错误（AddonManager）”。。。我今天几乎发疯了，因为所有的组件都是在上周内逐步安装的，最后我解决了这个问题。 以下是解决方案和说明： geckodriver v.0.16.0“仅与Selenium 3.4及更高版本兼容”（如其页面所述）。 一周前，selenium 3.3.1是最后一个版本。截至4月21日，selenium3.4.0已发布。

---

我不得不从头开始重新创建项目，重新添加Selenium罐。由于某些原因，在旧项目上简单地替换它们并没有起到作用。

请尝试下面的代码

String Firefoxdriverpath="C://Users//Ashish//Downloads//geckodriver-v0.16.0-win64//geckodriver.exe";
System.setProperty("webdriver.gecko.driver", Firefoxdriverpath);
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);  
driver.close(); 

---

请告诉我这是否有效。

我看不到您的代码中有任何重大错误。但您需要遵循以下特定准则：

在声明

字符串Firefoxdriverpath

时，您需要使用单前斜杠，即“/”

e、 g.

String Firefoxdriverpath=“C:/Utility/BrowserDrivers/geckodriver.exe”

或者您需要避开背面的斜线，即“\\”

e、 g.
String Firefoxdriverpath=“C:\\Utility\\BrowserDrivers\\geckodriver.exe”

让我知道这是否适用于您。
我也有同样的问题。
帮助的是使用
driver.quit（）而不是
driver.close（）
我也遇到过类似的问题，但最终还是通过下面这个为selenium 3.4功能更改的小代码解决了-

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

capabilities.setCapability("marionette", false); // true gives that Javascript error (AddonManager is not initialized)

使用Firefox版本时出现此错误：45.9.0；Selenium 3.4.0和Gecko驱动程序：16.1

解决方案：降级至gecko 16.0并使用：
System.setProperty（“webdriver.firefox.marionete”，“Path”）

希望这有帮助。
您使用的gecko驱动程序版本是什么？gecko驱动程序版本geckodriver-v0.16.0-Win64查看我的答案并更新状态。谢谢。我删除了旧项目，重新创建了新项目，并添加了jar文件，仍然显示这个错误。嗨，今天早上我在配置企业计算机时再次遇到它。在这里，从[link]（）切换到geckodrive v.0.15.0是有效的。让我知道它是否对您有效。只需通过[link]（），在更改的部分中有几点。不确定是否有帮助：1）SendKeysParameters（用于元素Send Keys和Send Alert Text命令）已更新为字符串文本字段。2） 默认情况下禁用Firefox中的Flash和插件容器，这将有助于缓解许多用户在删除带有driver.quit的会话时报告的“Firefox插件容器已停止编写”问题，没有登录，它正在退出浏览器。不，它仍然是相同的。它将收到相同的错误，firefox也不是closing@AshishJain-请下载geckodriver的旧版本以检查测试。这可能是由于mozilla和geckodriver之间的兼容性。还可以尝试改变壁虎河的保存位置。在我的机器里工作得很好。
