Hey! When I want to go to I get an error message with the title "Warning: Potential Security Risk Ahead". Below the title it says: "Nightly detected a potential security threat and did not continue to If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. has a security policy called HTTP Strict Transport Security (HSTS), which means that Nightly can only connect to it securely. You can’t add an exception to visit this site."

I don't think PayPal is in-secure.

I tried many answers I found here, like going to about:config and changing security.tls.version.max from the default of 4 to 3 etc.

hi, paypal is using an insecure symantec certificate - firefox is gradually revoking trust in those and as you are using a nightly build you're one of the first users noticing:

a temporary workaround would be setting security.pki.distrust_ca_policy to 1 (but don't forget to reset that preference to the default later on once most common websites have adapted)
