Mozilla Public License 2.0 Requirements. Open source software licenses fall into two categories: permissive and copyleft. Copyleft licenses, in turn, come in two flavors: strong and weak. The Mozilla Public License 2.0 is in the latter group. The difference between the two forms of copyleft licenses lies in the scope of source code to be shared.

Therefore, minified JavaScript is the Executable form, and the responsibilities set out i...
The MPL uses "distribute" in the sense of delivery of a copy of the software to another person or entity. We do not use distribute to mean "make available" in the sense of "making functionality available over the web without delivery of a copy of the software." So e.g. in a web-based application, the code which runs on the server is not 'distribute...

Yes but, as with MPL 1.1, we strongly discourage you from doing so. It will almost certainly make your software much less popular and less widely used. Software developers and companies are already aware of and understand popular licenses like the MPL. If you create your own, they will have to perform a legal assessment of your changes - and may co...
