在尝试：

WebDriver driver=new FirefoxDriver();

我收到以下错误：

java.lang.NoSuchMethodError: org.openqa.selenium.Proxy.extractFrom(Lorg/openqa/selenium/Capabilities;)Lorg/openqa/selenium/Proxy;
  at org.openqa.selenium.firefox.FirefoxDriver.dropCapabilities(FirefoxDriver.java:313)
  at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:191)
  at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:186)
  at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:182)
  at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:95)

这个问题在 ubuntu 上的 firefox 更新到 32.0 版本后就开始了，我尝试安装 28.0 版本但仍然没有工作。

有任何想法吗？提前致谢

像curiosu所说的将驱动程序版本更改为 2.39 后，出现一个新错误：

解决方案：我终于设法解决了这个问题，我将 selenium webDriver 版本从 2.42.2 更改为 2.39.0 并将 firefox 版本从 32.0 降级为 28.0

在 Windows 7 上更新 FireFox 32 和 Selenium Firefox Webdriver 2.40.0 时遇到了同样的异常。我将在这里发布我的解决方案，也许它不能解决您的问题，但它可能是其他有同样问题的人的解决方案搜索后降落在这里。

不知何故，selenium-remote-driver它没有得到正确更新，而它存在于selenium-firefox-driver. 我的解决方案是将远程驱动程序添加到我自己的 POM 中：

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-firefox-driver</artifactId>
    <version>2.43.1</version>
</dependency>
<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-remote-driver</artifactId>
    <version>2.43.1</version>
</dependency>

我不得不重新启动我的 IDE (IntelliJ) 并重建项目，但之后它工作了。

最终配置：

  • 火狐 32.0.3
  • Selenium FireFox 驱动程序 2.43.1
  • Selenium 远程驱动程序 2.43.1

请尝试较旧的 FF 构建。目前我也观察到此类问题 FF build no 32 with latest selenium 但是在将更改恢复到较旧的构建后，我的问题得到成功解决。

Try to use an older version of FirefoxDriver.

Use the older FirefoxDriver (e.g.: 2.39) with Firefox 32.

您在两者之间遇到了一些兼容性问题。最简单的方法是找到与 ubuntu 32.0 兼容的版本

如果在导入 jar 后第一次执行 selenium 代码

右键单击项目->构建路径->配置构建路径...->订购和导出->获取 JRE 库下方的 selenium java,server-standalone jars->确定

重新执行代码，它会工作。
