I have firefox. I am trying to open up the Tracfone.com to find out how many minutes I have left. and it can't open the website because it says that it is not a secure site. I used to be able to open this site.
I just tried it using Chrome and got right onto the website. I don't have a tracfone so I can't go any farther than the login page, but it looks OK to me. So I tried with Firefox and also got in just fine. FF is up to v57 now. Have you updated it lately? I'm on a Mac but I don't think that should make a difference.
