Can't open Paypal because of potential security risk.
Hey! When I want to go to paypal.com 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 www.paypal.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.
www.paypal.com 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.
Additional System Details
- Shockwave Flash 30.0 r0
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0
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: https://blog.nightly.mozilla.org/2018/08/14/symantec-distrust-in-firefox-nightly-63/
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)
