First at all, never use other Proxifier or proxy router than the one originally pre-installed in FraudFox. And never use the built-in proxy settings in the browsers. Only use Proxifier with the rules correctly as shown in the next snapshot:
For private socks5 provided with user:password do this:
- Open Proxifier, go to Profile and choose Proxy Servers
- Click Add and, enter your socks Address and Port
- On the Protocol field, select HTTPS Protocol
- On the Authentication field, select Enable and enter your username and password.
