"I believe that Mozilla can make progress in privacy, but leadership needs to recognize that current advertising practices that enable 'free' content are in direct conflict with security, privacy, stability, and performance concerns -- and that Firefox is first and foremost a user-agent, not an industry-agent.

"Advertising does not make content free. It merely externalizes the costs in a way that incentivizes malicious or incompetent players to build things like Superfish, infect 1 in 20 machines with ad injection malware, and create sites that require unsafe plugins and take twice as many resources to load, quite expensive in terms of bandwidth, power, and stability.

"It will take a major force to disrupt this ecosystem and motivate alternative revenue models. I hope that Mozilla can be that force."
