firefox-container-proxy VS temporary-containers

There's a first-party way and a third-party way to do this

Firefox Multi-Account Containers divides your browsing into separate color-coded tabs. Allows you to set up proxies and then assign each proxy to a container. Thereafter, each request coming from a particular tab in the container will use the appropriate proxy. electricheat explains, "I use [it] all the time. Either for different accounts, or for having certain tabs use certain proxy configurations."

I don't have a solution, but a potential part of a solution. If you're using Firefox, this addon allows to chose different proxies (and hence different IPs) for different containers. Should you find one Mullvad server that works (perhaps one that was recently added), you could make sure that your Netflix container always goes through that server, regardless of what server the app is connected to.

Additionally, you can have proxy servers configured per each container with this extension: https://addons.mozilla.org/en-US/firefox/addon/container-proxy/

I know 2 firefox addons, that support Proxy binding for each container - from Mozilla Multi Account Containers https://addons.mozilla.org/en-US/firefox/addon/multi-account-containers/ - separate addon for proxy Container Proxy https://addons.mozilla.org/en-US/firefox/addon/container-proxy/

Its developer passed away in January, but there's no reason to stop using it. It still works fine.

I use the Firefox container extension all day https://github.com/stoically/temporary-containers. If this isn't included, it'd be a deal killer for me. I'll check it out.
