License structure of the Mozilla Firefox:The main identity of the Mozilla Firefox is that it is free & open source software application, which is used to access the internet. This web browser is developed under tri-license agreement called as MPL/GPL/LGPL. In which MPL stands for Mozilla Public License, GPL stands for GNU General Public License and LGPL stands for GNU Lesser General Public License.
The MPL is free software license for open source software application like Firefox. The version1.0 of MPL was developed by the Mitchell Baker. The next tri-license GPL is developed & written by the Richard Stallman for the product of the GNU. In addition, this license is used by the Linux kernel.
The third license LGPL was published by the Free Software Foundation. It was planned as a negotiation between the strong-copyleft GNU General Public License and liberal licenses like BSD licenses and the MIT License.
The main advantage of this tri-license is to give permission to anybody look, transform & reallocate the source code. In addition, various software applications are released according to these tri-agreements. The recognized examples for that are Netscape, Flock & Songbird that are developed by using source code from Firefox.
There is certified end-user assemblers of Firefox which are circulated from Mozilla are licensed under the Mozilla EULA. The Firefox & artwork which are the trademark name, crash reporter like the proprietary Talkback are not considered under the tri-license. So their use is controlled by the EULA, which means end user license agreement for Mozilla project. So all of these EULA restrictions & agreement like clickwrap which are incorporated in the versions of Windows, the Foundation of Free Software consider these assembling as proprietary software.
Previously, the web browser like Firefox was certified exclusively under the MPL & it has been assessed by the Free Software Foundation for being weak copyleft. This license gives permission in inadequate ways that is privately owned derivative works.
In addition, it cannot possible to link the source code under MPL with the code, which is under the GPL or LGPL. So by giving attention to this concern, Mozilla Organization licensed the Firefox repeatedly web browser under the tri-license format i.e. MPL, GPL & LGPL. Therefore, by re-licensing, it is free for the developers to select the license under which they will take delivery of the source code.
