Annotated Mozilla Public License, version 1.0 - Since legal documents are difficult for non-lawyers to read, Mozilla has in the past provided a version of the license which contains informal explanations of various sections of the license, in the form of hyperlinks. Note that these explanations are not the license. The explanations are not a legal document, or legal advice. If you need to know exactly what the license requires, you need to read and understand the license itself; if you need legal advice, you need to talk to a lawyer. The annotations are merely a good faith effort to explain the license in simpler language.
