DNS leaks are regarded as a widespread issue, quite apparent in looking into tor configurations, though I personally agree (?) that this smacks of bad programming, perhaps in OS design (though again, this tends to be regarded as more of an issue with diverse proxying). Isolating TBB in iptables has proven problematic, since it lacks a native UID, etc.
It's not that hard to reconfigure Tor browser to work with standalone
Tor. In Debian, debian-tor typically has uid 108, as I recall. Then you
can allow only debian-tor process to access eth0 or wlan0.
> 2. To operate Tor with the full range of transports: I have started looking at the possibility of operating debian-tor with the transports included in TBB, ie. pointing tor at the pluggable transports and libs in the TBB data and Tor folders, but would love some help with this. This would give the best of both.
That's an excellent idea.

Yes, isolation by network namespace would be even better than iptables,
I think. But still less secure than isolation by VMs. Or using Qubes. Or
better, hardware isolation.
