Security

“Individuals’ security and privacy on the Internet are
fundamental and must not be treated as optional.”
  - Mozilla Manifesto Principle 4

The Mozilla Security community provides leadership in security by building security features, testing software and systems, and leading industry standards to ensure that individuals retain the ability to make meaningful choices about security and privacy on the Internet.

This page documents the security-related activities for Mozilla and how to join us.

Reporting Security Issues

Mozilla relies on the security community to help secure our products and websites by reporting security issues. Our preference is to receive bug reports via our bug tracking system Bugzilla, however emailing security@mozilla.org (preferably encrypted) is also an option.

Details on the way we classify security bugs can be found here.
