No matter where I try to go on the net, aside from the search engines, I get the same Secure Connection Failed error, and trying again does nothing. I've been using Edge, Chrome, and Brave to get to sites, and only come back occasionally to see if Firefox is working again. I even tried a fresh install, and reboot...still isn't working. My anti-virus is Vipre. I don't use any others. Why, after years of using Firefox, is it that suddenly it's useless?
