(Access Denied You don't have permission to access "http://www.costco.com/" on this server.

Reference #18.a7f00f17.1604805009.3a9c2ba )

That an error message I receive when trying to access www.costo.com on Firefox.

Earlier posts (2017) suggested this is a VPN problem. Disable the VPN and Cosco, com comes up. Well I use a VPN for security and I don't want to disable it to shop at Costco. I don't have that problem with Opera or Chrome, so it must be a Firefox problem. I like Firefox and prefer to use it, but this problem is disappointing. I'm surprised that no one involved with Firefox has solved it yet (no disrespect to the volunteers who spend many hours trying to fix things). It must be a tricky problem. Any ideas other than disabling my VPN. That's not going to happen.

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