You don't want a proxy. Get a VPN. Even then you need to turn off webrtc and other stuff. Make sure the VPN doesn't use port forwarding. Tor is NOT to be trusted. And besides, this site and many others may block some of the exit node IPs since spammers use Tor.
Tor is great if you're up to no good. Combine that with a double hop VPN you pay with bitcoins. Make sure you use an E-mail that you created with a Tor IP at least. Idea being you want nothing to trace back to you.
But all in all it's over kill. I use VPN.ac myself.
