Mozilla VPN

[n8chavez]

Does Mullvad VPN offers the ability to assign automatically a different location for each container in the browser?

BTW, to disable this or future nasty advertisements (Mozilla makes stupid decisions, indeed)

type about:config or open user.js file and

user_pref("browser.vpn_promo.enabled", false);

I am unsure. If mozilla allows you to use socks5 proxies through the VPN, like Mullvad does, than yes it can be done. I would assume so, since they use Mullvad's servers. This extension allows you to use per-container socks5 proxy addresses.
