Question

上下文：Firefox 50.0.2 64位，C＃，Visual Studio 2015，Windows Server 2012 R2，Azure，ClearScript.V8.5.4.7，Selenium.Mozilla.Firefox.Webdriver.0.6.0.1，Selenium.WebDriver.GeckoDriver。 Win64.0.11.1

我使用ClearScript包装Selenium对象以便在JavaScript中使用，即

    static JScriptEngine JSengine = null;
    ...
    JSengine = new JScriptEngine(WindowsScriptEngineFlags.EnableDebugging | WindowsScriptEngineFlags.EnableJITDebugging);
    ...
    JSengine.AddHostType("CSFirefoxDriver", typeof(FirefoxDriver));
    JSengine.AddHostType("CSFirefoxOptions", typeof(FirefoxOptions));
    JSengine.AddHostType("CSFirefoxDriverService", typeof(FirefoxDriverService));

我使用以下JS实例化Firefox

var driverService = CSFirefoxDriverService.CreateDefaultService();
driverService.FirefoxBinaryPath = "C:\\Program Files\\Mozilla Firefox\\firefox.exe";
driverService.HideCommandPromptWindow = true;
driverService.SuppressInitialDiagnosticInformation = true;
var options = new CSFirefoxOptions();
driver = new CSFirefoxDriver(driverService, options, CSTimeSpan.FromSeconds(30));

匹配的退出/处置代码是

try {
  driver.Quit();
} catch (E) {
  T.Error().Send("driver.Quit() failed.");
}

try {
  driver.Dispose();
} catch (E) {
  T.Error().Send("driver.Dispose() failed.");
}

（T是记录对象）

执行.Quit（）方法调用时，我得到以下对话框。

如果我注释掉.Quit（），那么我在.Dispose（）上也会这样。

其他论坛建议在Firefox的首选项中关闭硬件加速。这根本没有任何区别。

geckodriver论坛上还有一个问题，即声称有某种解决方法。它现在肯定没有修复。

Windows事件日志在这里并不特别有用，即

    </EventData>
</Event>

我从哪里开始？我可以回到PhantomJS，直到找到修复程序。

Answer 1

我遇到了同样的问题，我发现有人发布了here。目前，您可以降级到Firefox 48.0.2，直到它被修复。

Answer 2

仅在Windows 8.1上出现问题（我在win7＆amp; wind10上查看了它并且它正常工作）。所以你应该升级你的操作系统或降级浏览器。

Answer 3

如果使用了driver.quit（），则问题与webdriver.gecko.driver有关。我遇到了与selenium-java-3.0.1，FF v 50.1.0，Eclipse Kepler，JDK1.8相同的问题

解决方案：使用driver.close（）

Answer 4

使用这个。杀死每个firefox的进程和异常窗口的进程（在网上加入2个解决方案）：

string sProcessName = "firefox";

            if (driver.Capabilities.BrowserName == sProcessName)
            {
                // Special fix for firefox because of issue https://github.com/mozilla/geckodriver/issues/173
                // Kills all firefox processes

                Process[] oProccesses = null;
                bool bFound = true;

                while (bFound == true)
                {
                    bFound = false;
                    oProccesses = System.Diagnostics.Process.GetProcessesByName(sProcessName);

                    foreach (Process oCurrentProcess in oProccesses)
                    {
                        bFound = true;
                        //oCurrentProcess.Kill();


                        int waitTimeSecs = 2;

                        bool cleanExit = oCurrentProcess.WaitForExit(waitTimeSecs * 1000);
                        if (!oCurrentProcess.HasExited)
                        {
                            oCurrentProcess.CloseMainWindow();
                            System.Threading.Thread.Sleep(2000);
                        }

                        if (!oCurrentProcess.HasExited)
                        {
                            oCurrentProcess.Kill();
                            oCurrentProcess.WaitForExit();
                            // if an exception window has popped up, that needs to be killed too

                            foreach (var process in Process.GetProcessesByName("firefox"))
                            {
                                process.CloseMainWindow();
                                System.Threading.Thread.Sleep(2000);
                                if (!process.HasExited)
                                    process.Kill();
                            }
                        }


                    }
                }
                driver.Quit();
            }

Firefox通过GeckoDriver在Selenium 3.0.1中的.Quit（）上抛出异常
