The Tor Browser Bundle is free software under various licenses:

> Can I distribute Tor?

> Yes.

> The Tor software is free software. This means we give you the rights

> either for a fee or gratis. You don't have to ask us for specific
> permission.
> 
> However, if you want to redistribute the Tor software you must follow
> our LICENSE. Essentially this means that you need to include our
> LICENSE file along with whatever part of the Tor software you're
> distributing.
> 
> Most people who ask us this question don't want to distribute just the
> Tor software, though. They want to distribute the Tor Browser. This
> includes Firefox Extended Support Release, and the NoScript and
> HTTPS-Everywhere extensions. You will need to follow the license for
> those programs as well. Both of those Firefox extensions are
> distributed under the GNU General Public License, while Firefox ESR is
> released under the Mozilla Public License. The simplest way to obey
> their licenses is to include the source code for these programs
> everywhere you include the bundles themselves.
