Overview

LibreWolf is a privacy-focused version of Firefox that removes all telemetry

and cloud services. It's designed for users who want Firefox's privacy features but with even stricter privacy defaults. LibreWolf comes with uBlock Origin pre-installed to block ads and trackers, and it enables Enhanced Tracking Protection in strict mode by default. The browser uses Total Cookie Protection to isolate cookies and prevent cross-site tracking. LibreWolf includes Resist Fingerprinting, which makes all users appear identical to websites, preventing fingerprinting attacks. The browser is configured to automatically delete cookies and website data when you close it, ensuring no traces are left behind. LibreWolf disables features like form autofill, search suggestions, and link prefetching to minimize data exposure. The browser removes Firefox Sync and Pocket, so there are no cloud services that could collect your data. LibreWolf enables HTTPS-Only Mode by default, ensuring all your connections are secure. The browser is fully open source and community-maintained, giving you complete control over your privacy. LibreWolf is perfect for users who want maximum privacy without the telemetry and cloud services found in standard Firefox.
