Reviving a dead thread,
Substratum is great as mentioned before.
A new project, Lethean is just starting to make some good progress as well, works like a VPN, uses a blockchain running the Monero/CryptonightR consensus, making it pretty much untraceable. Not as easy to use as Substratum as it is still in developing phase, but I'm keeping my eye on it.
https://lethean.io/The Brave browser can work as an extra layer of security as well, just not really a TOR alternative like the above two.
