Description:
As part of the Librefox project, an attempt has been made to create a Firefox build aimed at increasing privacy and increasing security. Librefox is not an offshoot of Firefox and is built using the code of regular releases, which allows you to keep the browser up to date without lag. Librefox is characterized by changing settings and disabling unnecessary functionality. Available for download are builds for Linux, Windows and macOS, based on Firefox 64 (optional Librefox builds based on Firefox 60.4 ESR and Tor Browser 8.0.4 are available).
Additional Information:
Key Features:

Removed negatively affecting privacy built-in add-ons, update check code and components to send information about crashes;
Added firewall for add-ons that limits access to the network;
Settings are cleaned from embedded links to Mozilla servers and from calling functions that perform remote access to services (for example, loading of Google blacklists is disabled). By default, Librefox does not initiate any external connections;
More than 500 changes to the settings, aimed at improving security, privacy and performance. The ghacks-user.js and pyllyukko user.js collections are used as a template for changing settings;
The most important settings are protected from accidental changes, including additions, by moving them into the files mozilla.cfg and policies.json;
Disabled code for the accumulation of statistics and send telemetry;
As a recommended option, a dark theme is offered;
For installation, an optional set of own add-ons (Librefox-addons) is offered, which includes the Librefox Dark Theme (dark design theme), the Librefox HTTP Watcher (for HTTP without encryption changes the color of the address bar) and the Librefox Reload Button (moves the page reload button to the address bar );
A list of recommended add-ons that have undergone additional code review, including uBlock Origin, Browser Plugs Privacy Firewall, User Agent Platform Spoofer, First Party Isolation, Cookie Master
