The major problem was building a feature into the product that allowed for pushing add-ons without users knowledge much less active consent in the first place, there is no benign use for this kind of functionality.

Well it is - one could expect this sort of crap pushed by marketing/bizdev via management but the fact that Mozilla engineers actively collaborated on this is a sign of deep normative inadequacy among the people who are supposed to be the last line of defense against this sort of thing.

This is the opposite of comforting

Mozilla takes in about half a billion dollars per year, has anyone considered the consideration for which this money is being paid ?
