I agree with you. But a typical consumer will already be using Chrome, and has no reason to use Firefox.

If one of these advanced/niche technologies takes off, suddenly they will have a reason to use Firefox.

For Firefox to win back significant share, they need to do more than embrace fringe scenarios that normal people don’t care about. They need some compelling reason to switch.

IE lost the lead to Firefox when IE basically just stopped development and stagnated. Firefox lost to Chrome when Firefox became too bloated and slow. Firefox simply will not win back that market until either Chrome screws up majorly or Firefox delivers some significant value that Google cannot immediately copy.
