I do not have the time or the money to personally develop a secure web browser for the rest of the world, nor does any other individual. Your demand is unreasonable.
Moreover, I'm not demanding that Mozilla do something. I'm explaining what would have to change for me to be able to promote Firefox and contribute to reversing the declining market share. Short of not breaking the law I make no claims that Mozilla must do anything.
PS. Chromium is also free software. The difference is how Mozilla develops it's free software.
