What is the Mozilla Public License? A Comprehensive Legal Overview

Definition & Meaning

The Mozilla Public License (MPL) is a type of open-source software license that allows users to modify, distribute, and use software freely. It is abbreviated as MPL. Under this license, users can make changes to the software and share their modified versions with others. However, they must also release their changes under the same license terms as the original software, ensuring that the same freedoms apply to subsequent users. The MPL was initially created for the Netscape and Netscape Communicator browsers but is now applicable to a wide range of software projects.

  • Example 2: A company uses MPL-licensed software in their product and decides to modify it. They must ensure that their changes are also shared under the same licensing terms. (hypothetical example)
