I strongly discourage any user to use the tor network for the following
reasons:
1) Bundled browser is full of vulnerabilities (Remote access included)
2) Most of the nodes are owned by people who will perform Mitm attacks even
more if you use a layer 7 encrypted protocol. The chances of having an
outgoing node that does spy and perform Mitm are absolutely not 0.
3) The bandwith on that network is limited. Even if that network transport
all kind of dogshit, it does also transport legit traffic in countries where
acting out of the box might get you killed.
OP was "is OpenDNS safe to use?" ... My answer is no because you do not own
it.
