Dave, could you help the bug reporter, please.

What version of Selenium and Firefox are you using? Your user agent from comment 0 indicates Google Chrome, and not Firefox. I suspect this is a duplicate of bug 1103196, which was fixed in Firefox 52. Please try using Firefox 52 or later, with the acceptInsecureCerts capability set to true and report back.

Thanks for the reply. I am using Firefox 50.0.1 version and Selenium 30.0.1 version. Could you please let me the link to download Firefox 52 version please

(In reply to tharanya03 from comment #5) > How do I run Firefox nightly browser in my webdriver c# script. You will need to pass the path to the Firefox binary as a capability.

Please help. Details of capabilities can be found here: https://github.com/mozilla/geckodriver#webdriver-capabilities and to set these using C# see http://seleniumhq.github.io/selenium/docs/api/dotnet/?topic=html/T_OpenQA_Selenium_Remote_DesiredCapabilities.htm I'm going to close this as a duplicate of bug 1103196.
