Wow! Thank you for that tip. Block the machine's internet access with a firewall but connect the browsers over a SOCKS proxy. I mean, I do have a couple of containers up and running on a Raspberry Pi offering nothing but intranet SSH services while the containers are connected via OpenVPN to differnt VPN servers, so that I can use different browsers which connect via SOCKS each to one container in order to have one browser per country on one machine. It never occurred to me that I can use this same technique (but without OpenVPN) in order to disallow that machine to connect to the internet but still have a working browser...
