I uninstalled Avira Pro, which I had no problem with, but I wanted to try KIS. I installed KIS, and now on Firefox I can't log into my Outlook or Amazon. For Outlook I get a 'insecure connection' warning, and Amazon cookies seem to be disabled. It must be KIS as I just installed it, and had no issue prior. What's causing this? Is there a setting I should be tweaking that I don't know about? I can login however using Edge and Chrome, but FF is my preferred browser. I'm on Win 10.
