ERROR MESSAGE
I keep getting a messages anytime I try to visit a site which I have been to before? here's an example
"mail.aol.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site."

That means something changed the site contents during transmission, and the site publishes specification that if this happens the connection must fail hard.
Do you use any external VPN that might be trying to stuff advertising into the sites accessed? Or e.g. your modem is trying to show a page about weak signal or something? Any security/phishing/malware apps running, potentially scanning your secure connections?

I just use the VPN built in Firefox. I checked Edge and Chrome and got the same results? And it wasn't only one website, it seemed to be everyone that I had a username and password for? I ended up clearing the tmp files and cookies and it started working again. Thanks for the input.
