We’re the Firefox security team. Ask us anything about securing an open-source browser! (AMA)
Description
This content is an announcement of a live Ask Me Anything (AMA) session hosted by the Firefox security team on Reddit.

Reddit Discussion
Hi r/cybersecurity. We’re the Firefox security team. Join us in 30 minutes for a live AMA:
- Tom: u/tomrittervg - Principal Security Engineer - 10 years at Mozilla
- Freddy: u/mozfreddyb - Engineering Manager, Firefox Application Security - 15 years at Mozilla
- Christian: u/mozdeco - Principal Software Engineer - 15+ years at Mozilla
- Daniel: u/dveditz - Senior Staff Security Engineer - 22 years at Mozilla (contributing since Netscape, ‘98)
We work on everything Firefox, encompassing:
- Anti-Fingerprinting: Making Firefox users less unique to browser fingerprinters and combatting this tracking vector
- Security hardening: Making Firefox more resilient when under attack, e.g., by restricting capabilities in high-privilege contexts
- Product Security: Threat modeling, Security Reviews, Bug Bounty, Security Advisories, CVEs etc
- Fuzzing & LLM-based vulnerability identification: Design, implement and run fuzzers/test agents against select functions, API as well as the whole browser at cloud scale. We also co-maintain the required build configurations (eg AddressSanitizer)
- Web Security: We specify & develop new standards for the web platform with features like HTTPS-First, CSP, Sanitizer API etc. We collaborate across the industry in standards bodies like W3C, IETF and WHATWG
We have involvement in the broader Security & Privacy Protections of Firefox like Enhanced Tracking Protection, Cryptography, and Sandboxing. We also inspect & shepherd all security bugs from being filed to being fixed in an update.
We’ll be here at 12pm EDT for an hour answering questions about these areas, securing an open-source browser, and everything in between. Ask us anything!
