Can I configure the TOR Browser which comes with Whonix to use a proxy, so that it becomes an extra hop after the TOR exit node?
Sim.
Connecting as follows: Browser(workstation) > TOR(gateway) > exit node > proxy
Ou em outras palavras:
usuário - > Tor - > Proxy - > Destino
In contrast to the Tor Browser Bundle which connects to TOR via 127.0.0.1 under Whonix we have a different situation where we connect through the gateway to TOR. So a connection like I described maybe this might be possible.
Sim.
Is there any more recommended solution for proxy chaining under Whonix?
