Не могу запустить элементарный пример, ругается на сертификат

Привет! Пытаюсь открыть страницу:

System.setProperty("webdriver.gecko.driver","D:/geckodriver.exe");
open("https://github.com/"); 

Но не выходит, валится с ошибкой:

Exception in thread "main" org.openqa.selenium.WebDriverException: Reached error page: about:certerror?e=nssBadCert&u=https%3A//github.com/&s=badStsCert&c=UTF-8&f=regular&d=github.com%20%D0%B8%D1%81%D0%BF%D0%BE%D0%BB%D1%8C%D0%B7%D1%83%D0%B5%D1%82%20%D0%BD%D0%B5%D0%B4%D0%B5%D0%B9%D1%81%D1%82%D0%B2%D0%B8%D1%82%D0%B5%D0%BB%D1%8C%D0%BD%D1%8B%D0%B9%20%D1%81%D0%B5%D1%80%D1%82%D0%B8%D1%84%D0%B8%D0%BA%D0%B0%D1%82%20%D0%B1%D0%B5%D0%B7%D0%BE%D0%BF%D0%B0%D1%81%D0%BD%D0%BE%D1%81%D1%82%D0%B8.%0A%0A%D0%9A%20%D1%81%D0%B5%D1%80%D1%82%D0%B8%D1%84%D0%B8%D0%BA%D0%B0%D1%82%D1%83%20%D0%BD%D0%B5%D1%82%20%D0%B4%D0%BE%D0%B2%D0%B5%D1%80%D0%B8%D1%8F%2C%20%D1%82%D0%B0%D0%BA%20%D0%BA%D0%B0%D0%BA%20%D1%81%D0%B5%D1%80%D1%82%D0%B8%D1%84%D0%B8%D0%BA%D0%B0%D1%82%20%D0%B5%D0%B3%D0%BE%20%D0%B8%D0%B7%D0%B4%D0%B0%D1%82%D0%B5%D0%BB%D1%8F%20%D0%BD%D0%B5%D0%B8%D0%B7%D0%B2%D0%B5%D1%81%D1%82%D0%B5%D0%BD.%0A%D0%A1%D0%B5%D1%80%D0%B2%D0%B5%D1%80%20%D0%BC%D0%BE%D0%B3%20%D0%BD%D0%B5%20%D0%BE%D1%82%D0%BF%D1%80%D0%B0%D0%B2%D0%B8%D1%82%D1%8C%20%D1%81%D0%BE%D0%BE%D1%82%D0%B2%D0%B5%D1%82%D1%81%D1%82%D0%B2%D1%83%D1%8E%D1%89%D0%B8%D0%B5%20%D0%BF%D1%80%D0%BE%D0%BC%D0%B5%D0%B6%D1%83%D1%82%D0%BE%D1%87%D0%BD%D1%8B%D0%B5%20%D1%81%D0%B5%D1%80%D1%82%D0%B8%D1%84%D0%B8%D0%BA%D0%B0%D1%82%D1%8B.%0A%D0%9C%D0%BE%D0%B6%D0%B5%D1%82%20%D0%BF%D0%BE%D0%BD%D0%B0%D0%B4%D0%BE%D0%B1%D0%B8%D1%82%D1%8C%D1%81%D1%8F%20%D0%B8%D0%BC%D0%BF%D0%BE%D1%80%D1%82%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D1%82%D1%8C%20%D0%B4%D0%BE%D0%BF%D0%BE%D0%BB%D0%BD%D0%B8%D1%82%D0%B5%D0%BB%D1%8C%D0%BD%D1%8B%D0%B9%20%D0%BA%D0%BE%D1%80%D0%BD%D0%B5%D0%B2%D0%BE%D0%B9%20%D1%81%D0%B5%D1%80%D1%82%D0%B8%D1%84%D0%B8%D0%BA%D0%B0%D1%82.%0A%0A%D0%9A%D0%BE%D0%B4%20%D0%BE%D1%88%D0%B8%D0%B1%D0%BA%D0%B8%3A%20%3Ca%20id%3D%22errorCode%22%20title%3D%22SEC_ERROR_UNKNOWN_ISSUER%22%3ESEC_ERROR_UNKNOWN_ISSUER%3C/a%3E%0A
