I don't think you need a separate extension for proxy per container support. They support Mozilla's vpn thing by default but it cam be changed to any other proxy. Syntax is something like socks:host:port though I am mot sure about the GUI support to set it. I think I set it as part of Multi Account Containers. By the way I've heard an extension author say that containers are not required with the new strict isolation features.
