SecurityEngineering

We build security and user sovereignty into Firefox. Through this work, we encourage and promote these values on the open web.

We focus hard on ways to improve the privacy and security of all web users, in a Mozilla way that engages the community in our design and implementation decisions. These priorities are reflected in the projects this team manages, public evangelism and participation in relevant standards bodies to maximize adoption of new privacy & security mechanisms.

The open web is powerful; the huge number of people working on web standards and software is astonishing, and the rapid advancement of new businesses and technologies online magnifies the need for advances in mechanisms that enable secure systems and users' control over their presence online.

Who is involved

Security Engineering is led by Richard Barnes and Steve Workman, and mainly driven by Mark Goodwin, JC Jones, Kamil Jozwiak, David Keeler, Christoph Kerschbaumer, Francois Marier, Bob Owen, Sid Stamm, Daniel Veditz, Tanvi Vyas, Matt Wobensmith and Kathleen Wilson.

How We Work

The Security Engineering team works publicly like other Mozilla engineering teams. Continuously, we are focused on four top-level activities:

• Implement and Deploy
• Consult on Architecture and Design
• Research new Ideas
• Evangelize what we do

Experimental Things

We have a few feature proposals for things we might want to add to Firefox but that aren't currently scheduled:

• Contextual Identity
• Foreign Certificate Warning
• Master Password in the Password Manager
• Containers, private sessions and user profiles

From time to time we make add-ons to try out experimental features. Here are a few; let us know what you think!
