No. MinifiedJavaScript, while not an "executable" in the software engineering sense of the word, is difficult for humans to read, edit, and modify. As such, it is not "the preferred form for modification" and so it is not Source Code as defined by the license. 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...
MPL was written with software in mind, and should generally only be used for software. However, for consistency and simplicity, it may be appropriate to use the MPL for non-software works (such as documentation, images, and sound files) that are written primarily for use in MPL-licensed software.

So I basically have a choice between the MPLv2.0 or going with a permissive license. Some details on the license: https://opensource.org/licenses/MPL-2.0 https://www.mozilla.org/en-US/MPL/2.0/FAQ/ I've done some reading and here is my perceptions:
MPL is a practical license designed by Mozilla to enforce some kind of share-alike to the original library, while still encouraging people to make proprietary softwares and add-ons on top (including Mozilla itself), which is a practice that the FSF authorizes via LGPL but still considers harmful.
