CryFox is a privacy-first Firefox fork that strips away telemetry, blocks trackers by default, and hardens your browser against fingerprinting. Built for users who value speed and security without sacrificing usability.
Most browsers track your every move. CryFox doesn't. We removed the telemetry, disabled the data collection, and added powerful privacy protections that work silently in the background.
Built for privacy
Every feature is designed to protect your privacy without compromising experience.
Enhanced Privacy Protection
Strips away all telemetry and data collection. Your browsing history stays on your device, not in the cloud.
Tracker Blocking
Blocks known trackers by default. Built-in list updates automatically to catch new trackers.
Fingerprint Hardening
Randomizes fingerprint signals so advertisers can't build a profile on you across websites.
Performance Optimized
Without the tracking code, CryFox loads pages faster. Expect noticeably quicker browsing.
Why CryFox?
Your browser knows more about you than anything else. It deserves better.
Open Source
Every line of code is public. Audit it yourself or trust the community to do it for you.
No Corporate Interests
We're not funded by advertisers. Your data has no value to us because we don't monetize it.
Firefox Based
Built on Firefox for extension compatibility and web standards. Your favorite addons will work.
Actively Maintained
