For Mozilla to be successful they have to appeal to the largest demographic possible. I'd only ask that Mozilla make additional technical information easy to find and well laid out.

This is LastPass's page:

But that too you won't find when you use the app/extension normally.

Mozilla can do a lot of things that harm users or the general public but increase its success. Mozilla shouldn't do these things.

This neither harms users nor the general public, so I don't see relevance.
