The reality is we have quite a lot of issues with every distribution.
It is true that Debian gives us the least amount of hassle, though. I
suspect this may just be because we're lucky enough to be so strongly
socially connected to it. Because, man is it a rickety, towering
bureaucracy otherwise ;).

If Debian as a whole is willing to take our patches, that's great. We
hope they'll be merged into Mozilla eventually, so it could be a good
I agree that the approach above could work. If Debian wants to conjure
an alternate package that is really just a shell script that just
launches an /etc/skel copied TBB Firefox profile, this sort of thing
should be possible and fairly straight-forward. We can talk about this
on IRC, I suppose. It likely won't be a priority on Tor's side,
though. Also, I think we messed around a bit with remoting (aka new
window launching) on TBB Firefox, which may cause odd behavior for
your use case, or maybe not.. Erinn and sjmurdoch can tell you the
details of this (or I may be able to fetch them out of my subconscious
Our current working-plan is to provide an external repo, like we've
been forced to do for Ubuntu for other reasons. This ticket is
supposed to list the barriers to that:
But hey, so far there are none! :)
The long-term plan is to make Thandy the update future for our
packages. It is hardened against a lot of attacks that OS updaters are
not hardened against. We designed it because we thought it was the
future for all Tor packages, and I think this means we should start
acting like it. I think providing our own distro repositories is an
intermediate step to self-flagellate ourselves into actually bringing
As a last resort, could you replace torbutton with an empty package? I
can give you a replacement torbutton that refuses to toggle... Is this
against the debian social contract? :)

Right. I don't think that anyone is going to forget the value of
non-web communications. It's too built-in to the Internet and too
readily useful. However, the slightly more nuanced political realities
of this may make you sad:

Sure. That's what torsocks is for. It's a great Linux app, something
we dearly wished existed on Windows (and worked better on Mac OS).
I envision torsocks working with the system tor package, rather than
the TBB one. They should run on different ports:
The reason for this is that torsocks apps are poorly anonymized at the
application layer, and you don't want these to leak data (like your
username, hostname, etc) concurrent to your tor web traffic. The
easiest way to prevent that right now is to use your distro's tor and
our TBB at the same time.
(The long term way is to implement SOCKS password support both in Tor
and in Firefox:
I still consider torsocks an expert app, though.
So, in summary: Chaos and upheaval! Your bureaucracy is doomed!
Prepare for the paper shortage!
