LibreWolf

LibreWolf is a privacy-hardened fork of Firefox with aggressive privacy protections enabled by default, all telemetry removed, and security-focused configurations pre-applied. The open-source browser provides Firefox compatibility while eliminating Mozilla's data collection, pre-installed extensions, and privacy-compromising defaults for users who want maximum privacy without manual configuration.

Best For: Privacy advocates and security-conscious users who want Firefox without Mozilla's telemetry, data collection, or default privacy compromises, with enhanced protections enabled out-of-the-box.

Key Features

What privacy enhancements does LibreWolf add over Firefox?
All Mozilla telemetry completely removed. Enhanced Tracking Protection set to strict by default. DNS over HTTPS enabled automatically. WebRTC leaks prevented. Encrypted Client Hello (ECH) enabled. Cookies cleared on close. No Pocket, no sponsored content, no Firefox Accounts integration. Hardened Firefox preferences pre-configured.

How does LibreWolf handle tracking and fingerprinting?
Blocks third-party trackers, cryptominers, and fingerprinters by default. Canvas, WebGL, and audio context fingerprinting protections. User-Agent standardization reduces uniqueness. Referrer header minimized. First-party isolates prevent cross-site tracking. Network predictor and prefetching disabled to prevent data leaks.

Is LibreWolf compatible with Firefox extensions?
Full Firefox extension ecosystem available. uBlock Origin pre-installed for ad blocking. Extensions from Mozilla Add-ons work identically. No compatibility issues with standard Firefox add-ons. Extension updates work normally. Recommended privacy extensions documented.

What makes LibreWolf different from Tor Browser?
LibreWolf focuses on privacy through blocking and configuration, not anonymity through Tor network. Faster than Tor Browser (no onion routing overhead). Better for daily browsing where anonymity isn't critical. Can still use Tor via proxy if needed. Less fingerprintable than stock Firefox but more than Tor Browser's homogeneous configuration.
