About

Firefox fork that removes telemetry and data collection while shipping strict privacy and security defaults.

Analysis

OVERVIEW

A Firefox build with telemetry and data collection stripped, uBlock Origin included, and strict tracking protection as the default rather than an option.

LIMITS

Strict defaults break some sites, and the record notes the fingerprinting trade: heavy customization on a low-population browser can make an instance more distinctive, not less.

USEFUL FOR

Daily desktop browsing hardened at the defaults, without the latency of routing through Tor.
