Answer 1

这个问题通过geckodriver 0.15和selenium 3.3版本解决。

Answer 2

You need to download geckodriver. And then set

System.setProperty("webdriver.gecko.driver", "path\\to\\geckodriver.exe")

Check this link .

Answer 3

I had the same problem and fixed it with this. It seems it could not find the firefox binary

capabilities.setCapability("firefox_binary","C:\\Program Files\\Mozilla Firefox\\firefox.exe");

Answer 4

Same problem here. It was solved opening Eclipse/Netbeans with admin privileges.

Answer 5

This worked (linux mint, opensuse thumbleweed, win7) with

libraryDependencies += "org.seleniumhq.selenium" % "selenium-firefox-driver" % "3.0.1"

geckodriver.exe -V geckodriver 0.13.0

if (System.getProperty("os.name").toLowerCase().contains("linux")) {
  println("загружены настройки os.name=linux")
  System.setProperty("webdriver.chrome.driver", "bin/chromedriver")
  System.setProperty("webdriver.gecko.driver", "bin/geckodriver")

}else{
  System.setProperty("webdriver.chrome.driver", "bin\\chromedriver.exe")
  System.setProperty("webdriver.gecko.driver", "bin\\geckodriver.exe")
  System.setProperty("webdriver.ie.driver", "bin\\IEDriverServer.exe")
  System.setProperty("webdriver.edge.driver", "C:\\Program Files (x86)\\Microsoft Web Driver\\MicrosoftWebDriver.exe")
  System.setProperty("webdriver.opera.driver", "c:\\XXX\\operadriver.exe")

  System.setProperty("webdriver.opera.path","""C:\\Users\\user\\AppData\\Local\\Programs\\Opera""")
  System.setProperty("webdriver.opera.binary","""C:\\Users\\user\\AppData\\Local\\Programs\\Opera\\launcher.exe""")
  //
}

...

      case
        "firefox" => {
        println(" подгружаем Веб-драйвер: geckodriver")
        //iniprofile = new ProfilesIni()
        //ffprofile = iniprofile.getProfile("default")
        dc = DesiredCapabilities.firefox()
        dc.setCapability("gecko", true) // как выйдет драйвер, так и установить
//        dc.setCapability(FirefoxDriver.PROFILE, ffprofile); //FirefoxDriver.PROFILE = “firefox_profile”;
        remote = new FirefoxDriver(dc)
      }

but, for Remotewebdriver-connection if previous session failed,cancelled or aborted we get error:

[info] XXXX.E011_WebDB6292 *** ABORTED ***
[info]   org.openqa.selenium.SessionNotCreatedException: Session is already started (WARNING: The server did not provide any stacktrace information)

Answer 6

I ran into the same problem today, and it appears that not being admin on my laptop is actually an issue . To resolve it

• Install in a non admin way Firefox (just need to click on no when Windows ask for privilege elevation)

• Use the exe path (for my system something like C:\\\\Users\\\\MyUserName\\\\AppData\\\\Local\\\\MozillaFirefox\\\\firefox.exe ).

  It actually solved the issue.

Answer 7

If you are using the latest GekoDriver then better to update the Selenium library versions as well. The above issue is related to the Selenium version.

Answer 8

Alternatively if you dont want to download the Gecko driver, you can downgrade the Firefox version to 44.
