“unknown error”,“message”:“connection refused”,“stacktrace” while trying to use firefoxprofile through GeckoDriver with Selenium on Mac OS X

问题

I am getting connection refused error while creating a firefox driver.

System.setProperty("webdriver.gecko.driver", "path to gecko driver");
FirefoxOptions options = new FirefoxOptions();
options.setLogLevel(FirefoxDriverLogLevel.FATAL);
options.setAcceptInsecureCerts(true);
options.addArguments("-profile", "./firefoxprofile");
options.setHeadless(true);
LOGGER.info("Completed setting firefox optons");
WebDriver driver = new FirefoxDriver(options);

Log:

Web server is running and I could able to test it with curl command and I tried with 777 permissions on gecko driver bin file.

Also updated Gecko driver to latest version (0.24.0)

While working with Selenium v3.x, GeckoDriver v0.24.0 and Firefox Quantum v65.0 to use a new Firefox Profile on every run of your Test Execution you can use the following code block :

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
FirefoxOptions options = new FirefoxOptions();
options.setProfile(new FirefoxProfile());
options.setLogLevel(FirefoxDriverLogLevel.FATAL);
options.setAcceptInsecureCerts(true);
options.setHeadless(true);
WebDriver driver = new FirefoxDriver(options);
driver.get("https://www.google.com");

You can find a detailed discussion in Cannot resolve constructor FirefoxDriver(org.openqa.selenium.firefox.FirefoxProfile)

Your configurations looks good.

I had a similar problems in Linux.

• In my case the solution was test with all versions of gecko driver and with one of them, it worked.

• Also you can check if the o.s user of your IDE (eclipse, intellij) is the same user of the firefox. In my case, eclipse was starting with root but firefox could not start with root user.

I hope this help you.

I was facing the same problem in Windows using python. Make sure that your Firefox browser version is also the latest one.

After searching a lot, I finally found it was because a previous instance of the browser was running. Keep in mind, not another instance like one opened by me but an instance which was previously opened by selenium. If you can, close all the background browser processes. I restarted my system and it works perfectly fine as long as I remember to do browser.quit().

If you stop the program before closing the object properly, there is a chance the background instance will keep running unless eclipse or whichever IDE you are using closes it.
