We need more Firefoxes.
We need more browsers that treat their users, rather than publishers, as their customers. It’s the natural cycle of concentration-disruption-renewal that has kept the Web vibrant for nearly 20 years (eons, in web-years).
We may never get another one, though.
The World Wide Web Consortium (W3C), once the force for open standards that kept browsers from locking publishers to their proprietary capabilities, has changed its mission. Since 2013, the organization has provided a forum where today’s dominant browser companies and the dominant entertainment companies can collaborate on a system to let our browsers control our behavior, rather than the other way.
