What is LibreWolf?
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.
LibreWolf is a free, open-source web browser built from Firefox's source code and modified specifically for privacy, security, and user freedom. It removes Mozilla's telemetry and data collection, ships with uBlock Origin and hardened privacy settings pre-configured, and is not affiliated with Mozilla. LibreWolf is built for privacy-conscious users who want Firefox's engine and extension compatibility without the default tracking and who are comfortable with a browser maintained entirely by volunteers rather than a company. It's available for Windows, macOS, and most Linux distributions, and it's entirely free with no paid tier, donations, or commercial backing.
Standout feature: Ships with uBlock Origin and hardened privacy settings pre-configured out of the box, rather than requiring users to manually strip telemetry or install a content blocker themselves.
Biggest weakness: No mobile version (Android or iOS) is offered, and as a fully volunteer-run project with no company or funding model behind it, users get no commercial support, no guaranteed release schedule, and updates depend entirely on maintainer availability.
Pros
- Free and open source with no ads, telemetry, or data collection by default.
- uBlock Origin and privacy-hardened settings are bundled in, not left to the user to configure.
- Built on Firefox's engine, so most Firefox extensions and web compatibility carry over.
- Tracks upstream Firefox releases closely, so security patches arrive without a long lag.
Cons
- No official mobile app for Android or iOS, unlike Firefox itself.
- The project explicitly declines donations, so its long-term funding and maintenance depend entirely on volunteer time.
- No corporate or dedicated support channel; help comes from community Matrix, Reddit, and Lemmy spaces.
- Hardened default settings can break some sites' functionality until manually adjusted.
