Cannot Start The Driver Service On Http Localhost Selenium Firefox C !!top!! Info

using OpenQA.Selenium.Firefox;

IWebDriver driver = new FirefoxDriver(); driver.Url = "https://www.example.com"; using OpenQA

Alternatively, modify your hosts file to ensure “localhost” resolves to 127.0.0.1 (though this may affect other applications). IWebDriver driver = new FirefoxDriver()

The error message I see is:

: A system-level or corporate proxy environment variable forces local traffic through an outside proxy server, making localhost or 127.0.0.1 unreachable. driver.Url = "https://www.example.com"

FirefoxOptions options = new FirefoxOptions(); // Point this to your actual Firefox installation path options.BrowserExecutableLocation = @"C:\Program Files\Mozilla Firefox\firefox.exe"; FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(); service.Host = "127.0.0.1"; using (IWebDriver driver = new FirefoxDriver(service, options)) driver.Navigate().GoToUrl("https://example.com"); Use code with caution.
