These sort of "which-browser?" discussions come up regularly. In 2014 I would have been laying down 10-15 interesting extensions that gave Firefox capabilities that Chrome didn't have.

Instead the points raised here are

a) Perceptions

b) Design & marketing

c) Perception

d) Trust

Just saying, there used to be real technical ammo to bring to the table. Might have helped shore up the userbase if there were great reasons to use Firefox. Maybe users don't use software for its capabilities, but it isn't like Firefox is bringing much else to the table now.
