I just downloaded the portable version of Firefox. I can login without a problem, no errors. I'm even writing this from a Firefox browser. The issue you have is on your end or your ISP. Which antivirus do you have? Some of them will tamper with SSL certificates, we've seen this behavior on Aurora before. Also VPN like NordVPN can cause troubles.
Just windows defender. Honestly this just started two days ago. On Saturday it worked just fine. My ISP is comcast used by my family if that helps.
