Amazon.com site displaying "problem loading page"
Hello. I have just had Best Buy's Geek Squad complete some work on my PC. Now I cannot access my Amazon.com site, even though I have added it to my Kaspersky account. Firefox keeps displaying a "problem loading page" error. I am an Amazon customer. I also have NordVpn. How do I fix this, please? Thank you for any help that you can give.
