I would prefer something a bit more granular than changing my device's network configuration and sending all of its traffic through the same VPN. Just because I want to watch a movie through a server in another country doesn't mean that I also want my video chat app or stock trading app to take the same detour. Since this is Mozilla, how about a Firefox extension that passes all Firefox traffic through a VPN, like Tor Browser does, but doesn't touch any other app? That would differentiate it from most of the other VPN offerings out there. Currently my go-to solution is to set up a local SOCKS proxy with an SSH tunnel and point Firefox at it. It's good enough for testing, but not all services work properly when accessed that way.
