您的Selenium版本可能与您的Firefox版本不兼容。尝试安装旧的Firefox版本

  • 在安装旧版本之前，进入Firefox并关闭自动更新选项

    Firefox-->选项-->选项-->高级-->更新-->检查更新，但让我选择安装更新

  • 转到此处，安装新版本和旧版本

    您不必卸载Firefox，只需安装您想要安装的版本即可。您可能需要尝试几个版本，直到找到正确的版本

    • 您需要卸载当前安装的Firefox。使用最低版本18.0.1重新安装FF，这真的很有效。

    我刚刚在使用maven设置JBehave for WebDriver时遇到问题。我强迫JBehave以以下方式使用更高版本的selenium，这对我很有用：

    <dependency>
    <groupId>org.jbehave.web</groupId>
    <artifactId>jbehave-web-selenium</artifactId>
    <version>${jbehave.web.version}</version>
    <exclusions>
        <exclusion>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>2.33.0</version>
</dependency>

    
org.jbehave.web
jbehavewebselenium
${jbehave.web.version}
org.seleniumhq.selenium

2.33.0
    我遇到了完全相同的问题，我通过将Firefox版本降级到27.0.1解决了这个问题。对我来说，最有效的方法是使用最新的Firefox（目前为32.0.2）和最新的selenium

        <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>2.43.1</version>
    </dependency>

    
org.seleniumhq.selenium
硒爪哇
2.43.1
    版本2.43.1起作用，2.42.1不起作用。

    当WebDriver版本与Firefox版本不匹配时，java编译器会抛出此错误。确保您的WebDriver和Firefox都是最新版本。

    更新到selenium-server-standalone-2.44.0.jar对我有用（）

    似乎您需要浏览器、selenium驱动程序和selenium服务器的适当组合

    Ubuntu 14.04、Firefox 35.0.1和selenium webdriver 2.44.0在Ruby on Rails应用程序中为我工作。
    自从我更新了Chrome之后，Chrome就不起作用了，即使是最后发布的驱动程序也是如此。

    我想，这篇文章已经涵盖了它：[[1]：虽然在撰写本文时，下面的答案是正确的，但值得注意的是，FF驱动程序在FF 47之后将不起任何作用，并且在链接文章中找到答案之前，我遇到了这篇文章，因此将.post作为注释发布。我遇到了相同的错误，但使用了不同版本的软件。我曾经遇到过e今天，在FF 27.0.1中使用Selenium WebDriver 2.31也存在同样的问题。现在，在FF 27.0.1中使用WebDriver 2.39解决了这个问题。或者，如果浏览器是新版本，请更新Selenium而不是安装旧浏览器……我完全同意使用最新的FF/Selenium版本，而不是在不必要时降级
