Selenium geckodriver executes findElement 10 times slower than chromedriver (.Net)

Question

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

Answer 1

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\\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;

// DotNet Core workaround #2- Code page

CodePagesEncodingProvider.Instance.GetEncoding(437);
Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);

_driver = new FirefoxDriver(geckoService, ffOptions);
