<h1>Mozilla Foundation License Policy</h1>
 
<div class=version>
Version 2.0 draft 2
</div>
 
<h2>Introduction</h2>
 
<p>The Mozilla Foundation has created this formal policy governing licenses
to be used for source files stored in our code
repositories. Developers with check-in
privileges to the mozilla.org code repositories must comply with
this policy unless specifically advised otherwise in writing by
The Mozilla Foundation.</p>
 
<p>The following is a brief summary of the Mozilla Foundation
license policy:</p>
 
<ul>
<li>Newly-added code must be licensed under the terms pertaining
to that part of the repository to which it is added.</li>
 
<li>You must consult the licensing team before adding code
not under one of the mozilla.org-approved licenses.</li>
</ul>
 
<p>For the complete license policy see the following
sections.</p>
 
<h2>Definitions</h2>
 
<ul>
<li><b>Mozilla Code</b> is code in our repositories which originated with the Mozilla Project.</li>
 
<li><b>Third Party Code</b> is code in our repositories which did not originate with the Mozilla Project. It is usually, but not always, under its own specific license.</li>
 
<li><b>Product Code</b> means all files any part of which end up in nightly binaries of the
Mozilla family of Internet clients - Firefox, Thunderbird, SeaMonkey
and Camino. Note that this definition excludes the code of tools used merely to
build these products. Code may be both Product Code and Third Party Code.</li>
 
<li><b>Support Code</b> is code in our repositories which originated with the Mozilla Project but is not Product Code.</li>
</ul>
 
<p>Please see the diagram for the relationship between the four definitions. XXX DIAGRAM NOT AVAILABLE YET</p>
 
 
<h2>Acceptable Licenses</h2>
 
<ol>
<li><p>The following license (the "Mozilla tri-license") is acceptable in all circumstances:</p>
 
<ul>
<li>
MPL/GPL/LGPL triple license,
allowing use of the file under the terms of any one of:
<ul>
<li>The [http://www.mozilla.org/MPL/MPL-1.1.html Mozilla Public License, version 1.1]
or later (MPL)
<li>The [http://www.gnu.org/licenses/gpl-2.0.html GNU General Public License, version 2]
or later (GPL)
<li>The [http://www.gnu.org/licenses/lgpl-2.1.html GNU Lesser General Public License, version 2.1]
or later (LGPL)
</ul>
</li>
</ul>
 
<p>For new source files
please use the
[http://www.mozilla.org/MPL/boilerplate-1.1/index.html boilerplate license notice]
appropriate for the type of file you are creating. Please don't copy boilerplate from existing files.</p>
 
<li><p>The following license is acceptable for trivial pieces of Support Code, such as testcases:</p>
 
<ul>
<li>Creative Commons Public Domain Dedication, using the following boilerplate:
<blockquote><pre>
Any copyright is dedicated to the Public Domain.
http://creativecommons.org/licenses/publicdomain/</pre></blockquote>
</li>
</ul>
 
<li><p>The following licenses are acceptable only for Support Code in
directories whose files are already under the license in question,
as outlined later in this policy:</p>
 
<ul>
<li>The [http://www.mozilla.org/MPL/MPL-1.1.html Mozilla Public License, version 1.1]
or later (MPL) alone
<li>The [http://www.mozilla.org/MPL/NPL-1.1.html Netscape Public License, version 1.1]
or later (NPL) alone
<li>MPL/GPL dual license, allowing use of the file under the terms of either of:
<ul>
<li>The [http://www.mozilla.org/MPL/MPL-1.1.html Mozilla Public License, version 1.1]
or later (MPL)
<li>The [http://www.gnu.org/licenses/gpl-2.0.html GNU General Public License, version 2]
or later (GPL)
</ul>
</ul>
 
<li><p>For Third Party Code, you should use the license pertaining to that
code when modifying it or adding new files to it, and the tri-license when
adding Mozilla-specific files such as build system files. See below for
a list of directories this applies to.</p>
 
<li><p><span style="color: red">All Product Code must be under either the tri-license or, for Third Party Product Code, a license compatible with all three sets of terms in the tri-license (e.g. BSD-like licenses).</span> The purpose of this rule is to make sure that users of our code can take and use the same code under any one of the three licenses; no group is disadvantaged.</p></li>
 
</ol>
 
 
<h2>Repositories</h2>
 
<p>The Mozilla project runs a number of source code repositories, plus repositories for documentation and websites which are out of scope for this policy. Here is a list of repositories plus a summary of the licensing situation.</p>

<h2>Copying Code</h2>
 
<p>You may copy code between files with identical licensing terms, or between files where the target file has a subset of the licenses of the source file (e.g. MPL/LGPL/GPL -> MPL). For any other transfer, consult the licensing team first.</p>
 
<hr>
 
<p>This concludes the list of licenses acceptable to mozilla.org
for use with Mozilla code. If you happen to find a file in the
Mozilla source tree under a license which does not conform to the pattern above,
please report it to
[mailto:licensing@mozilla.org licensing@mozilla.org].</p>
