FF: 52.6 ESR version Selenium : 3.5.2 Gecko driver : v0.15
FirefoxProfile profile = new FirefoxProfile();
System.setProperty("webdriver.gecko.driver", "D:/geckodrivers/geckodriver-v0.15.0-win64/geckodriver.exe");
profile.setAcceptUntrustedCertificates(true);
profile.setAssumeUntrustedCertificateIssuer(true);
driver = new FirefoxDriver(profile);
I am using this code and still getting insecure connection error. If I use capabilities, the url itself is not opening in FF browser. Issue not replicating in Chrome and IE.
