Exception: Year, Month, and Day parameters describe an un-representable DateTime

[Yasir Kuşcu]

I want to install the mozilla plugin.

When I define the xpi file it gives this error

Year, Month, and Day parameters describe an un-representable DateTime

Selenium.WebDriver: 3.141.0

Selenium.Support: 3.141.0

please help me solve this problem

the code is here:

            const string extension1 = @"C:\user_agent_switcher_and_manager-0.3.4-an+fx.xpi";

            FirefoxOptions options = new FirefoxOptions();

            FirefoxProfile profile = new FirefoxProfile();

            profile.AcceptUntrustedCertificates = true;

            profile.AddExtension(extension1);

            options.Profile = profile;

            using (IWebDriver driver = new FirefoxDriver(options))

            {

                //var ext = new FirefoxExtension("C:\\user_agent_switcher_and_manager-0.3.4-an+fx.xpi");

                //ext.Install(profile.ProfileDirectory);

                WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));

                driver.Navigate().GoToUrl("https://www.google.com/ncr");

                Console.ReadKey();

                driver.Quit();

            }

Doesn’t look like a Selenium issue from the intro action you’ve given. What is throwing the error, the browser?

It’s an issue in the .NET bindings with some zip files, which is what Firefox extensions are. The issue is fixed in the 4.0 alpha versions.

browser does not open

Visual studio gives this error during compilation.

I tried another xpi extension, it still didn't

I'm using c#

I upgraded to Selenium Alpha 4.0. Now he started to make such a mistake.

OpenQA.Selenium.WebDriverException: 'Cannot find a file named 'C:\Users\Yasir\source\repos\selenium.net\selenium.net\bin\Debug\webdriver.json' or an embedded resource with the id 'WebDriver.FirefoxPreferences'.'
