Selenium 3.0.1 crashes FireFox 51.0.1 during driver.quit() @ Win 7 Home Premium & GeckoDriver 0.13.0

问题

Win 7 and FireFox is running in German language.
Win 7 has all available updates installed.

Same for 32 and 64 Bit GeckoDriver! (my Win 7 ist 64 Bit; my FireFox is 32 Bit).

Same for GeckoDriver 0.14.

Is this just a problem on my PC ?

driver.quit() is working on my InternetExplorer without a problem.

package JS_JFrame1;                                       

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

public class SeleniumFireFoxMinimal1 {  



public static void main(String[] args) throws InterruptedException {

    System.setProperty("webdriver.gecko.driver", "e:\\geckodriver.exe");

    WebDriver driver = new FirefoxDriver();                 

    driver.get("http://www.toolsqa.com");                    

    Thread.sleep(5000);                                   

    driver.quit();                                        

}                                                            

}

Other selenium commands like these work perfectly well:

    element = driver.findElement(By.id("sinp"));              

    System.out.println( "Element found!");                   

    element.clear();                                                

    element.sendKeys("black");                                      

    element.submit();

回答1:

set browser.tabs.remote.autostart.2 to false.

FirefoxOptions options = new FirefoxOptions();
options.BrowserExecutableLocation = Settings.Default.FirefoxBinary;

>>>> profile.SetPreference("browser.tabs.remote.autostart.2", false);
FirefoxProfile profile = new FirefoxProfile();
....
options.Profile = profile;
driverSet.Driver = new FirefoxDriver(options);

回答2:

The issue is related to the fact firefox started using multiprocess environment from firefox version >= 50, and it seems selenium is unable to handle it.

Adding the following lines should resolve this issue :

FirefoxProfile ffProfile = new FirefoxProfile();
ffProfile.setPreference("browser.tabs.remote.autostart.2", false);
WebDriver driver = new FirefoxDriver(newFirefoxOptions().setProfile(ffProfile));

回答3:

It's a known Firefox/geckodriver issue with quitting driver, see here for more details.

It appears in some FF versions, some say it's fixed, some say it's not. I couldn't find better solution for this so I switched on 'old' Firefoxdriver and FF v47.0.2 which works fine.

回答4:

I found a workaround for this. My code is in C#

Utility.Instance.KillProcess("firefox");
System.Windows.Forms.SendKeys.SendWait("{ESC}");
Utility.Instance.KillProcess("geckodriverserver");

Hope it will help you.
