Summary

LibreWolf is a free, open-source browser based on Firefox that puts privacy, security, and user freedom first. It is available for Linux, macOS, and Windows. Its default setup includes uBlock Origin with custom filter lists, strict Tracking Protection, Resist Fingerprinting, and disabled WebGL. It removes cookies and website data when you close the browser and enables Total Cookie Protection. HTTPS-only mode and stricter TLS/SSL negotiation rules are also enabled. DuckDuckGo and Searx are among its listed privacy-conscious search providers. LibreWolf disables telemetry, including crash reports, studies, and personalized recommendations; the project says it does not collect data and lacks the infrastructure to do so. Updates usually follow an upstream stable Firefox release within three days, but the browser cannot update itself automatically. DRM playback is off by default and can be enabled in settings. The built-in password manager is disabled, and the project suggests using another option. There is no Android version in development, according to the FAQ, which recommends IronFox instead. LibreWolf is not affiliated with Mozilla.
