Looks like almost everybody would be worse off if Firefox went away and looks like nobody gives a shit if it's going away in part due to uncompetitive behaviour on iOS and largely because they don't seem to have a handle on the situation, investing left and right and not focusing on the browser.
Here's a thought, Mozilla does a lot of political campaigning, how about campaigning for open app stores and death to no other browser engine? Why not do this which seems like a do or die situation for them?
