TheOldNet Browser Proxy

I recently bought something on Etsy from what seems to be the creator of this service. It has a serial port on it, and it behaves kind of like a Hayes modem. Except the AT commands actually configure a wifi connection, and you dial up servers (telnet-like?) that behave like BBSes over the Internet.

I went to try this out, but didn't want to change the proxy settings for my entire browser (I'm interleaving work and screwing off here, need the "real" internet to still work).

So, feature request for Mozilla: Can I specify different proxy/DNS settings per container? All sorts of cool stuff could be enabled if I allowed one container type raw Internet access, and another one restricted through piHole type filtering, or a full on proxy server.

Using the port to specify year is neat. Although there is a Y64ki problem.
