How to connect your VPN to Firefox?

Question

VPN

There is a VPN server that I want to connect to Firefox. The browser itself works through a proxy.
I checked several browser extensions - they all offer a certain set of VPNs and there is no way to enter the address I need.
Does anyone know an extension with the ability to register your own VPN server?

Answer 1

Vpn connects not to the browser, but to the OS, i.e. the answer to your question is NO

Answer 2

Set up a proxy server on the server with your vpn, and specify this proxy in the mozilla settings.
