Hello, While I don't recommend you doing this since security warnings are there to protect your data from insecure sites, potential scams, and identity theft. So in proceeding to do so, is at your own risk. On the error page, click the '''Advanced button.''' Click Accept the Risk and Continue. For errors related to expired or self-signed certificates, you can add a '''permanent exception.''' Navigate to Firefox Settings and then select Privacy & Security. Scroll down to the Certificates section and click View Certificates. On the Servers tab, click Add Exception, enter the website's address, and click Get Certificate. Click Confirm Security Exception. Please be careful!
