Insecure Connection
I've been trying forever to setup something as a shop using PayPal, however, whenever I go to PayPal's sandbox website to test a purchase, I am told it is an insecure website. I have tried to add an exception to the entire site itself, and it simply doesn't work. This is very annoying as I prefer FireFox, and I have had to resort using Chrome as a backup, which hogs computer resources and doesn't have any of my passwords saved, so it makes my process very long and tedious.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

I don't have any anti-virus installed that could be doing this in the first place. I can attempt these fixes, but I, personally, do not see how they pertain to me as I don't have any security software installed.
What specific error page do you get? Is this SEC_ERROR_UNKNOWN_ISSUER or something else?
