Topic: Setting development mode in iceweasel-uxp or trusting local address

response.set_cookie('cookie_key', secure=True, httponly=True, samesite='Strict', max_age=1800)

Above code in python-flask ensures that the cookie is sent over a secure https connection only and prevents cross scripting attacks to some extent. The issue I get while developing is iceweasel-uxp shows is untrustworthy since it isn't encrypted for development testing.

response.set_cookie('cookie_key', httponly=True, samesite='Strict', max_age=1800)

Above code works well. My question is
Is there a development mode in iceweasel-uxp OR how do I make a trusted address?

Today, the forces which make the rich richer and poor poorer have their roots in computer security. Never has it been more important to work towards abolishing the power of the powerful.

Let's use hyperbola or other libre OSes and strive towards stateless hardware (Rutkowska 2015). Let's use PinePhone and shun Android and iPhone which pretend to be secure.
