Your connection is not secure - using Selenium.WebDriver v.3.6.0 + Firefox v.56

Question

I\'m writing tests with Selenium + C# and I face an important issue because I didn\'t found solution when I test my site with secure connection (HT

Answer 1

For me, the profile setting AcceptUntrustedCertificates was not enough, I also had to set option security.cert_pinning.enforcement_level. My startup looks like

// no idea why FirefoxWebDriver needs this, but it will throw without
// https://stackoverflow.com/questions/56802715/firefoxwebdriver-no-data-is-available-for-encoding-437
CodePagesEncodingProvider.Instance.GetEncoding(437);
Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);

var service = FirefoxDriverService.CreateDefaultService(Environment.CurrentDirectory);
service.FirefoxBinaryPath = Config.GetConfigurationString("FirefoxBinaryPath"); // path in appsettings

var options = new FirefoxOptions();
options.SetPreference("security.cert_pinning.enforcement_level", 0);
options.SetPreference("security.enterprise_roots.enabled", true);

var profile = new FirefoxProfile()
{
    AcceptUntrustedCertificates = true,
    AssumeUntrustedCertificateIssuer = false,
};
options.Profile = profile;

var driver = new FirefoxDriver(service, options);

Answer 2

You are setting the properties on the profile. The FirefoxOptions has a property AcceptInsecureCertificates, set that to true.

Forget the profile, this is what you want:

var op = new FirefoxOptions
{
    AcceptInsecureCertificates = true
};

Instance = new FirefoxDriver(op);

Answer 3

It works for me for following settings (same as above):

My env:

win 7

firefox 61.0.2 (64-bit)

Selenium C# webdriver : 3.14.0

geckodriver-v0.21.0-win32.zip

==============================

FirefoxOptions options = new FirefoxOptions();

options.BrowserExecutableLocation = @"C:\Program Files\Mozilla Firefox\firefox.exe";

options.AcceptInsecureCertificates = true;

new FirefoxDriver(RelativePath,options);
