While I understand why a lot of consumers have dropped Firefox for Chrome as Android took off, I think there's another really big reason Chrome is so dominant. They provide .admx files which allows businesses with a Windows ADDS environment to manage Chrome and it's configuration in a very granular way. I remember pushing it hard as a sysadmin because it was a realistic alternate to IE we could centrally manage. That's the sort of thing that, because of privacy concerns nowadays, Mozilla could use to displace significant market share with privacy-conscious businesses. There needs to be a comparable "Firefox for Work" sort of option that can be centrally managed.
