LibreWolf
Verified working Sep 17, 2026
A hardened Firefox fork that strips telemetry and bundles tracker blocking.
LibreWolf is an independent desktop browser built from current Firefox stable releases with privacy- and security-focused defaults. It removes Mozilla telemetry and experiments, disables DRM, includes uBlock Origin, and ships with privacy-oriented search options.
Why it stands out
- Keeps close to Firefox stable, so users get familiar extension and website compatibility while using stricter defaults.
- Removes telemetry, experiments, adware-style extras, and DRM rather than merely adding privacy settings on top.
- Ships with uBlock Origin already included, reducing setup needed for content blocking.
- Community-run and open source, with public repositories and discussion channels for contributions and issue reports.
Good to know
- Disabling DRM can prevent playback on some streaming or protected-media sites.
- The listed installers target desktop operating systems; it is not presented as a mobile browser.
- Privacy-hardened defaults may require occasional setting changes for websites that expect standard Firefox behavior.
- LibreWolf is independent and not affiliated with Mozilla, despite being based on Firefox.
Under the radar: Before changing random about:config values, check LibreWolf’s Settings and Overrides documentation; it explains which defaults are intentional and how to adjust them without fighting future updates.

Privacy-conscious desktop users who want Firefox compatibility with fewer built-in data-collection features. Replace a mainstream browser with one that has stronger anti-tracking defaults out of the box. Browse with uBlock Origin preinstalled instead of configuring an ad blocker separately. Use a Firefox-based browser on Windows, macOS, Linux, or OpenBSD while keeping the codebase open source.
