# LibreWolf review

A free, open-source Firefox fork focused on privacy and security, with telemetry stripped out and uBlock Origin bundled by default.

By Noah — last updated & pricing verified September 15, 2026.

> **LibreWolf** is a custom, independent build of Firefox whose primary goals are privacy, security, and user freedom: it strips out Mozilla's telemetry, sponsored content, and other data-collection features while keeping Firefox's rendering engine and extension compatibility intact.

The browser ships pre-configured with hardened privacy settings, private search engine defaults like DuckDuckGo, and uBlock Origin bundled in from install rather than added separately. It tracks upstream Firefox releases closely so it stays current with security patches. LibreWolf's source code moved from GitLab to Codeberg, and the project explicitly declines to accept donations, stating it wants to avoid becoming dependent on funding and keep contributors free of donor expectations.

Because LibreWolf is entirely volunteer-run with no company or paid tier behind it, there's no commercial support contract, dedicated account team, or guaranteed release cadence beyond what the community delivers — a tradeoff privacy-focused users accept in exchange for a browser with no corporate telemetry.
