I installed Bitdefender Total Security Program 2016 and now I can't open any websites in latest version of Firefox. When I uninstalled Bitdefender, Firefox worked fine. I keep getting "connection not secure" error message. I can open websites using Windows Internet Explorer. How can I fix Firefox?

This fixed my problem. Thank you. It's wonderful that forum people can find fixes to problems and be able to pass on the solution to others. I don't think I would have been able to find the solution myself in a timely manner. I would have uninstalled Bitdefender just so I could keep on using Firefox.
