LibreWolf is a custom and independent fork of Firefox, focused on privacy, security, and freedom. It ships with uBlock Origin and hardened settings by default.
LibreWolf follows the same registry layout as Firefox, substituting LibreWolf for Mozilla in key names.
Policies can be enforced via HKLM\SOFTWARE\Policies\Mozilla\Firefox (shared with Firefox) or via policies.json.
Profile data lives in %APPDATA%\librewolf\Profiles\ — no registry storage for user data.
When set as the default browser, it writes handlers to HKCU\SOFTWARE\LibreWolf\Capabilities.
