I have several saved login URL's that I've had for years. Today - when I click on any of them, I receive am insecure connection message from Firefox indicating that "The owner of input.mozilla.org has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website." As you can see, I can't even get Firefox to go to it's own webite. So I look at the certificate information and Avast is listed as the issuing authority. I have a snapshot of the information, however I can't figure out how to send you the image.
