What makes it different

LibreWolf takes Firefox and changes its defaults with privacy in mind. The goal is a browser that is private out of the box, without the user spending an evening in the settings. Telemetry and other data collection are switched off, tracking protection is stricter, and privacy-oriented choices are made for search and fingerprinting protection. Because the engine is Firefox, websites work as they do in Firefox, and most Firefox extensions install as usual. The trade-off is convenience. Stricter settings can break some sites or make you log in again more often, and features that depend on Mozilla's online services may be off or missing. LibreWolf is a community project; its version numbers follow Firefox, with an extra suffix for the LibreWolf build.

How to install it

1. Open the official installation page and choose Windows.
2. Download the installer or use one of the package managers listed there.
3. Run setup, then import bookmarks from your old browser if needed.
4. Check the privacy settings once to see what is enabled, and relax them for sites you trust if something breaks.

Requirements

LibreWolf runs on current Windows versions, like the Firefox release it is built from. A PC that runs Firefox well will run LibreWolf too.

Updates and safety

Browser security depends on updates, and Firefox fixes reach LibreWolf through new builds. Check for new versions regularly on the official site, especially after Firefox security releases. Download only from librewolf.net or the project's repositories.

Moving from Firefox

LibreWolf keeps its profile separate from Firefox, so both browsers can live side by side while you test. Export bookmarks from Firefox as a file and import them, then reinstall the extensions you really use; fewer extensions also mean fewer ways to be tracked. Saved passwords are best moved through a password manager rather than left in any browser.

Price

LibreWolf is free and open source.

Who it suits

Users who like Firefox but want stronger privacy defaults, and people who prefer a browser that does not report to its developer. If you rely on sync across devices or on sites that break with strict settings, standard Firefox may be more comfortable.

Pros and cons

• Pro: privacy-focused defaults with no setup.
• Pro: Firefox engine and extensions.
• Pro: open source.
• Con: some sites break with strict settings.
