Sorry didn't find a similar question and maybe somebody can help.
Due to additional requirements we have to test our project not only with Chrome but with Firefox as well. When we simply changed a test context to Firefox it turned out that all calls of findElement took 10 times more time than with Chrome. All tests are completely ruined. We tried to use different test machines but the results are the same. The project is on Core .Net. For testing we use MSTest V2, Firefox 63 (64 bit) and Geckodriver 0.22 (64 bit) .
Very appreciate any help.
By referring to the previous answer, my issue was solved by below code.
string geckoDriverDirectory = "Path of geckodriver.exe"
FirefoxDriverService geckoService =
FirefoxDriverService.CreateDefaultService(geckoDriverDirectory);
geckoService.Host = "::1";
var firefoxOptions = new FirefoxOptions();
firefoxOptions.AcceptInsecureCertificates = true;
Driver = new FirefoxDriver(geckoService, firefoxOptions);
Yep. You’re definitely hitting the performance issue that is part of .NET Core. It doesn’t happen on Chrome, IE, or Edge, because the driver executables for each of those browsers (unlike geckodriver) listen on both the IPv4 and IPv6 loopback addresses. If you were to specify “::1” as the host for geckodriver with .NET, the problem would disappear.

A complete .Net Core webdriver for Firefox 7/14/2020:
// .Net Core workaround #1: Slow Firefox webdriver
string projectFolder = Directory.GetParent(Directory.GetCurrentDirectory()).FullName;
string geckoDriverDirectory = projectFolder + "\\netcoreapp3.1\\";
FirefoxDriverService geckoService =
FirefoxDriverService.CreateDefaultService(geckoDriverDirectory);
geckoService.Host = "::1";
var ffOptions = new FirefoxOptions();
ffOptions.BrowserExecutableLocation = #"C:\Program Files\Mozilla Firefox\Firefox.exe";
ffOptions.AcceptInsecureCertificates = true;
// This profile will by-pass *ALL* credentials. Note that Chrome uses Internet Explorer settings, so it does not need this.
// You must pre-setup the profile, by launching Firefox and doing phone authentication
// The profile's location is: C:\Users\<windows logon>\AppData\Local\Mozilla\Firefox\Profiles
// Without this, if your AUT uses SSO, you will always get prompted for the PIN or Two factor authentication
FirefoxProfile profile = new FirefoxProfileManager().GetProfile("Selenium");
ffOptions.Profile = profile;

CodePagesEncodingProvider.Instance.GetEncoding(437);
Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
_driver = new FirefoxDriver(geckoService, ffOptions);
In case anyone is trying gary.zhang's answer in Javascript, it looks like this:
let driver = new Builder()
.forBrowser('firefox')
.setFirefoxService(new firefox.ServiceBuilder('path_to_driver', host='::1'))
.setFirefoxOptions(new firefox.Options().headless())
.build();
Took me a bit of staring at it to figure out how to convert the syntax.

I have a requirement to switch from chrome to edge driver chromium
I am having issues trying to launch the browser as a different user. We need to open the browser with different users who have different roles and validate
To manually do this you would right click edge browser > shift and click Microsoft edge > Run as different user
I am using the following NuGet Packages:
MicrosoftEdge.SeleniumTools 3.141.2
Selenium.Webdriver 3.141.0
Microsoft Edge version
91.0.864.54
Previously with using chrome and the package Selenium.Chrome.Webdriver i was able to use the following
service.StartupDomain = ""
service.StartupUserName = ""
service.StartupPassword = ""
service.StartupLoadUserProfile = true;
However with MicrosoftEdge.SeleniumTools 3.141.2 i am unable to find a similar solutions. Does anyone know an equivalent solution?
Current code below
EdgeDriverService service = EdgeDriverService.CreateChromiumService(driverpath, msedgedriverExe);
var edgeOptions = new EdgeOptions();
edgeOptions.UseChromium = true;
service. ???
edgeOptions. ???
IWebDriver driver = new EdgeDriver(service, options)
I am using the current opera driver with Selenium for testing of a website (so that we can support Opera as an approved browser for our website). I code in C#.
When I open Opera I get a popup at the top of the screen that states:
You are using an unsupported command-line flag: --enable-blink-features=ShadowDOMV0. Stability and security will suffer.
I currently setup my Opera instance with the following code:
string operaExeLocation = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile) + #"\AppData\Local\Programs\Opera\74.0.3911.107\opera.exe";
OperaDriverService service = OperaDriverService.CreateDefaultService(#"C:\Opera\", "operadriver.exe");
var operaOptions = new OperaOptions
{
BinaryLocation = operaExeLocation,
LeaveBrowserRunning = false
};
driver = new OperaDriver(service, operaOptions);
I suspect that the unsupported flag can be turned off in the operaOptions - but I haven't found any documentation on how to do that. Please help if you are familiar with setting up the driver.
I'm using selenium 3.14 with geckodriver 0.24, I'm using following code to run the existing profiles I have already created for my different accounts.
FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.Proxy = pro; //my proxy object
firefoxOptions.AddArgument("-profile " + path); //path to the profile
FirefoxDriverService ffDriverService = FirefoxDriverService.CreateDefaultService();
ffDriverService.BrowserCommunicationPort = 2828;
PropertiesCollection.Driver = new FirefoxDriver(ffDriverService, firefoxOptions);
I have multiple profiles each with a different proxy. Right now, the browser is started and everything works very well for the first profile, but once I dispose the browser and start a new one with new profile and proxy, the driver opens the same last browser. I've tried many solutions and have changed selenium to old versions but no luck.
One thing I noticed in the console is that when driver opens the browser, it runs a command on console like this:
1561625708285 mozrunner::runner INFO Running command: "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe" "-marionette" "-profile C:\\Users\\Usr\\Desktop\\fprofiles\\pf1" "-foreground" "-no-remote"
if I run this command from cmd the profile issue remains there:
"C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe" "-marionette" "-profile C:\\Users\\Usr\\Desktop\\fprofiles\\pf1" "-foreground" "-no-remote"
If I remove the " from command and make it complete text it will look like this
"C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe" -marionette -profile C:\\Users\\Usr\\Desktop\\fprofiles\\pf1 -foreground -no-remote
I cloned the selenium project of OpenQA and tried to debug there but that also uses geckodriver.exe and I guess geckodriver.exe is responsible for getting arguments and passing to firefox.
Last but the least option will be to compile geckodriver(which has been developed in RUST) once again as per my consent but the programming language is RUST and that's going to be a long long job for achieving what I need.
Has anyone faced the same problem? How can I get it fixed?
Try loading browser profile based on it's name. An example with profile called 'selenium_profile':
public static WebDriver driver;
public static String driverPath = "C:\\Users\\pburgr\\Desktop\\selenium-tests\\FF_driver_0_23\\geckodriver.exe";
public static WebDriver startFF() {
FirefoxOptions options = new FirefoxOptions();
ProfilesIni allProfiles = new ProfilesIni();
FirefoxProfile selenium_profile = allProfiles.getProfile("selenium_profile");
options.setProfile(selenium_profile);
options.setBinary("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
System.setProperty("webdriver.gecko.driver", driverPath);
driver = new FirefoxDriver(options);
driver.manage().window().maximize();
return driver;
}
It must not be static so you can parse name of desired profile in argument.
Is there any way how to force webdriver/internetexplorerdriver to open a site in compatibility mode. Every time I run my tests by Nunit all the history and compatibility mode list (where was my site listed before) are cleaned.
I can't change the code of the site. Can I add item to compatibility mode list or open site in specifi version of IE (I have 11 and I need open it in 7 with doc type 5).
Unfortunately no, unless you change the source code. As a workaround I use VMS. If you want to use the same route consider using free VMs from Microsoft. See my another answer related to question here
This is better description of my issue: I need to test a site that I can't edit. The site works only in compatibility mode in my IE 11 (it is made for ie 7 doc type 5). I want to run tests and cookies should be cleaned before that. But if I set "EnsureCleanSession = true" it cleans compatibilty list in IE besides cookies. Because of it, it's not possible to test the site.
I have found possible solution, but I have to test it... I've found out that compatibility list is in registry and I can load its value before it is cleaned and set the value again:
const string keyName = #"HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\BrowserEmulation\ClearableListData";
var a = Registry.GetValue(keyName, "UserFilter" , "Return this default if NoSuchName does not exist.");
// value of registry is removed
Registry.SetValue(keyName, "UserFilter", a);
Console.ReadLine();
But as I said, I don't know if it will do the trick...
[UPDATE]
Ok, it works with small work-around (because IE must be restarted after change in registry)
[SetUp]
public void SetUp()
{
//read the compatibility mode list from registry
const string path = #"HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\BrowserEmulation\ClearableListData";
const string key = "UserFilter";
var regValue = Registry.GetValue(path, key, "Return this default if NoSuchName does not exist.");
//run IE driver with cleaning of cookies and history
var options = new InternetExplorerOptions
{
IntroduceInstabilityByIgnoringProtectedModeSettings = true,
EnsureCleanSession = true
};
_driver = new InternetExplorerDriver(IeDriversPath, options);
//cloase IE
_driver.Quit();
_driver.Dispose();
//put the compatibility mode list back into registry
Registry.SetValue(path, key, regValue);
//run IE driver without cleaning of cookies and history
options.EnsureCleanSession = false;
_driver = new InternetExplorerDriver(IeDriversPath, options);
}
I created a console application (with target: .Net Framework 4) and added the next references:
Selenium.WebDriverBackedSelenium.dll
ThoughtWorks.Selenium.Core.dll
WebDriver.dll
WebDriver.Support.dll
static IWebDriver driver = null;
if (driver == null)
{
ChromeOptions options = new ChromeOptions();
options.AddArguments("--start-maximized");
driver = new ChromeDriver(#"C:\selenium\net40", options);
// it opened a new window (about:blank)
}
driver.Navigate().GoToUrl("http://www.facebook.com");
but nothing is happen.
I use: ChromeDriver 26.0.1383.0

any help appreciated!
For the later versions of Chrome (27+), there is a new shiny ChromeDriver:
http://code.google.com/p/chromedriver/downloads/list
Note the section within the summary on the page...
ChromeDriver server for win32 (v2.2.215849.dyu) supports Chrome v27-30
Also, you should remove the Thoughtworks & WebDriverBackedSelenium references, they are not required and you don't seem to be using them.
