The Multi Account Containers extension has an Advanced proxy settings at the bottom when you go in to Manager Containers. I have a go based socks proxy running on docker somewhere. I enter the details for that there. Syntax is socks://ip:port .

I am aware of foxyproxy. It works OK. I was using it until the containers gained proxy support.
what VPN provider can you use with this extension?
