The Mozilla Public License (MPL) is a free and open-source software license developed by the Mozilla Foundation. It allows developers to use, modify, and distribute software while ensuring that modifications to the original code remain open and accessible to the public. MPL is designed to balance the interests of both open-source and proprietary software developers. It permits the integration of MPL-licensed code with other software, provided that any changes to the MPL-licensed components are shared under the same license. This encourages collaboration while protecting the original authors' rights.
