LibreWolf

LibreWolf is an independent, open-source Firefox variant for people who want privacy protections switched on by default. It suits desktop users willing to keep the browser updated and handle passwords elsewhere. The trade-off is a deliberately restrictive setup that asks for more maintenance than a typical browser.

Overview

LibreWolf combines tracking defenses, anti-fingerprinting settings and stricter connection security, while disabling browser telemetry. The project says it collects no data and has no infrastructure to do so. It is not affiliated with Mozilla, though it is based on Firefox and usually receives updates within three days of an upstream stable release.

That update cadence is reasonably prompt, but there is no automatic update capability: staying current is the user's responsibility. Cookie and website data are deleted when the browser closes, which helps limit persistence but can mean signing in again or rebuilding site preferences. DRM playback is disabled by default and must be enabled in settings for sites that require it.

Key features

Tracking and fingerprinting controls

LibreWolf includes uBlock Origin with custom default filter lists and enables Tracking Protection in strict mode. Resist Fingerprinting is on by default, and WebGL is disabled. These defaults suit privacy-conscious users who prefer protection without assembling extensions themselves; stricter settings may be inconvenient for people who depend on persistent site data or WebGL.

Security and privacy defaults

HTTPS-only mode and stricter TLS/SSL negotiation rules add safeguards around connections. Total Cookie Protection is enabled, alongside deletion of cookies and website data on close. DuckDuckGo and Searx are among the privacy-conscious search providers the project lists. The browser disables telemetry, including crash reports, studies and personalized recommendations.

Everyday trade-offs

The built-in password manager is disabled, and LibreWolf recommends using another password manager. That is a sensible fit for people who already have a separate password workflow, but a drawback for anyone who expects the browser to store and fill credentials. Cross-device sync is supported, although LibreWolf's strict cookie handling and desktop-only platform availability may still make it a less seamless choice for users moving between devices.

Security issues can be reported by PGP-encrypted email, but there is no bug bounty program. Users can ask questions in the Matrix room, Reddit community or Lemmy community.

Pricing

LibreWolf is free and open source, with no free trial. The LibreWolf plan costs nothing and describes a community-driven open-source browser. There are no paid tiers to weigh against its manual update and separate password-manager requirements.

Platforms

LibreWolf is available for Linux, macOS and Windows. There is no Android version in development, and the project recommends IronFox for Android users. Its desktop focus is a clear limitation for anyone who wants the same browser across desktop and phone.

Who it's for

Choose LibreWolf if you want a free Firefox-based browser with strict tracking and cookie protections, anti-fingerprinting defaults and no telemetry, and you are prepared to update it yourself. Look elsewhere if you need an Android build, browser-managed passwords, automatic updates or DRM playback enabled out of the box.

Pros and cons

• Strong protections enabled by default: uBlock Origin, strict Tracking Protection, Resist Fingerprinting and Total Cookie Protection reduce the need to configure a privacy setup from scratch.
• Minimal browser telemetry: the project says telemetry is disabled and that it does not collect data.
• Manual upkeep: users must install updates themselves, despite updates usually following Firefox stable releases within three days.
• Separate password management: the built-in manager is disabled, so users need another way to store credentials.
• Desktop-only availability: there is no Android version, and DRM playback needs to be enabled when required.

Alternatives

Verdict

LibreWolf is a strong choice for desktop users who want a free, open-source Firefox variant with substantial privacy protections already enabled. Its main reason to choose is the breadth of those defaults; its main reason to look elsewhere is the responsibility it puts on users to manage updates and passwords, alongside the lack of Android support.
