utilizing the fact that the same origin policy is not enforced within server-to-server communication

JSONP is a relic of the past and shouldn’t be used due to numerous limitations (e.g., being able to send GET requests only) and many security concerns (e.g., the server can respond with whatever JavaScript code it wants — not necessarily the one we expect — which then has access to everything in the context of the window, including localStorage and cookies).

Adding layer of settings and complexity for the end user might also bring bad practices to keep a comfortable use of app’s by installing snap without confinement…

It would be best to offer an official way to allow installing local, unsigned extensions, and make the option configurable only by root, while also showing appropiate warnings about the potential risks of installing unsigned extensions.

I appreciate the vigilance, but it would be even better to actually publish a technical reasoning for why do you folks believe Firefox is above the device owner, and the root user, and why there should be no possibility through any means and configuration protections to enable users to run their own code in the release version of Firefox.

We must consider introducing sensible default options in Firefox, while also educating users and allowing them to override certain features, instead of placing marginal security benefits above user liberties and free choice.
