The most important thing to a regular user, is that their websites work. But for websites to work, the developer had to test in Firefox. So, Firefox's alienation of power users has hurt its regular userbase.

"What would you do if you were the head of Mozilla" sure reads a lot like "what do I want Firefox to do".

Firefox lost the battle for average users against Chrome. But it's always been a favourite of power users for a reason. It's time to listen to power users again, or be extinguished (incidentally, that's the third stage of EEE).
