<p>Why not recommend Mozilla branded software like Firefox,
Thunderbird, and SeaMonkey? As explained in our <a rel="nofollow"
class="external text"
href="https://www.gnu.org/philosophy/free-sw.html">Free Software
Definition</a>, all four freedoms must be available on both a
commercial and non-commercial basis. Mozilla's trademark policy
serves to limit Freedom 2 to gratis distribution only, making the
software nonfree.</p>

<h3>Modifications</h3>
<p>If you're taking full advantage of the open-source nature of
Mozilla's products and making significant functional changes, you
may not redistribute the fruits of your labor under any Mozilla
trademark, without Mozilla's prior written consent. For example,
if the product you've modified is Firefox, you may not use Mozilla
or Firefox, in whole or in part, in its name. Also, it would be
inappropriate for you to say "based on Mozilla Firefox". Instead,
in the interest of complete accuracy, you could describe your
executables as "based on Mozilla technology", or "incorporating
Mozilla source code." In addition, you may want to read the
discussion on the "<a
href="https://www.mozilla.org/en-US/foundation/trademarks/poweredby/faq/">Powered
by Mozilla</a>" logo.</p>
<p>In addition, if you compile a modified version, as discussed
above, with branding enabled (the default in our source code is
branding disabled), you will require Mozilla's prior written
permission. If it's not the unmodified installer package from <a
class="moz-txt-link-abbreviated" href="http://www.mozilla.org">www.mozilla.org</a>,
and you want to use our trademark(s), our review and approval of
your modifications is required. You also must change the name of
the executable so as to reduce the chance that a user of the
modified software will be misled into believing it to be a native
Mozilla product.</p>
<p>Again, any modification to the Mozilla product, including adding
to, modifying in any way, or deleting content from the files
included with an installer, file location changes, added code,
modification of any source files including additions and
deletions, etc., will require our permission if you want to use
the Mozilla Marks. If you have any doubt, just ask us at <a
href="mailto:trademarks@mozilla.com">trademarks@mozilla.com</a>.</p>

<p>Debian has permission to redistribute modified copies of Firefox
with the Firefox branding, Parabola GNU/Linux-libre (and every
other distro) does not. These Parabola packages are still
maintained as a result:
