Add-ons • Re: Theme licensing question

If you're combining LGPL'd portions into an MPL 2.0 licensed work, you should allow the MPL 2.0 work in Source Code Form to be available under the LGPL too. This would only be possible if the MPL'd work isn't marked "Incompatible With Secondary Licenses" , and the Executable Form (I guess the XPI-packaged result would be it?) isn't sublicensed under terms that limit or alter the recipients’ rights under the LGPL (EDIT: I just realized that requirement is only for the source code). These articles by Mozilla's licensing team might help:
