Ask HN: Why is Firefox losing marketshare and how would you save it?
To me, they absolutely shunned their core audience -- people who wanted greater flexibility and configurability than existing browsers could give them.  As a power user who used to have Firefox humming along exactly how I wanted it (thanks to things like Keyconfig, etc.), I now really perceive next to no difference between Firefox and Chrome.  Yes, there's philosophical reasons that make them differ.  But in terms of what they offer to the end user?  There's no difference.  They neutered themselves.
