I'm using the Acrobat Customization Wizard for Mac and I selected "Disable PDF Rendering in browsers" and also "Enable Feature Lockdown" with a plist file that has cServices>bUpdater disabled. That all works great; the browser plugins are omitted and all the cloud services are disabled.
However, it still installs an extension for Firefox named "Adobe Acrobat DC - Create PDF 15" that asks for permission to be enabled for every new user that opens Firefox. Adobe talks about the extension here. How can I deploy Acrobat DC on a Mac without the extension?
