vopono

I strongly suggest that you use something like Network Namespaces through Vopono[0] or Gluetun[1] if you use a commercial VPN for "privacy" or "security" aka torrenting and shitposting. Relying on these clients is always a gamble and if your software (Browser, Torrentclient, etc.) cannot know you public IP only the internal IP of the VPN you are also safe against some exploits and misconfigurations a desktop client won't protect you against.

Vopono (https://github.com/jamesmcm/vopono): "vopono is a tool to run applications through VPN tunnels via temporary network namespaces. This allows you to run only a handful of applications through different VPNs simultaneously, whilst keeping your main connection as normal. vopono includes built-in killswitches for both Wireguard and OpenVPN."

you might want to check out vopono, i've gotten it working with firefox and its nice https://github.com/jamesmcm/vopono

Mullvad are the best VPN service out there by far IMO - and writing vopono: https://github.com/jamesmcm/vopono - I used many of them! I think most VPN users just want something to access different Netflix catalogues though, and Mullvad doesn't play that cat and mouse game.

vopono - a tool to run individual applications through VPN connections on Linux: https://github.com/jamesmcm/vopono I wrote it based on some scripts I had, and then added Wireguard support and configuration generation. I'm now working on making a proper backend so it can be used as a library (i.e. to run a few requests through different VPN connections, e.g. for web scraping for websites with geolocation-sensitive content), and also to learn a lot more about Linux system calls. Eventually I'd like to expand that to use the network namespaces and firewall rules to allow for different virtual network configurations so I could use it for testing out distributed systems development too.
