This project aims to fix privacy and security issues related to Firefox without forking the project.
Librefox uses gHacks-User.js and Pyllyukko-User.js, more than 500 additional privacy/security/performance settings, patches, Librefox-Addons (optional) and a cleaned bundle of Firefox (updater, crashreporter and Firefox's integrated addons that don't respect privacy are removed).
mozilla.cfg and policies.json, those settings cannot be changed by addons/updates/Firefox or unwanted/accidental manipulation; To change those settings you can easily do it by editing mozilla.cfg and policies.json.> Librefox : Features ............................................................... > Librefox : Download ............................................................... > Librefox : Capture ................................................................ > Addons : Librefox Addons .......................................................... > Addons : Recommended Addons ....................................................... > Addons : Recommended Addons Settings .............................................. > Addons : Reviewing Addons Source Code ............................................. > Addons : Other Useful Addons Listing .............................................. > Wiki : Extensions Network Firewall ................................................ > Wiki : IJWY (I Just Want You To Shut Up) .......................................... > Wiki : Apply Librefox Manually .................................................... > Wiki : Edit Locked Settings ....................................................... > Wiki : Settings Index ............................................................. > Wiki : Cookies Settings ........................................................... > Wiki : Tracking Protection ........................................................ > Wiki : Comparing Changes And Updates .............................................. > Wiki : Documentation .............................................................. > Wiki : Librefox Dark Theme ........................................................ > Wiki : Tuning Librefox ............................................................ > Wiki : Librefox ESR ............................................................... > Wiki : Tor Compatibility .......................................................... > Wiki : DRM Compatibility .......................................................... > Wiki : Building And Packaging ..................................................... > Browser Tests : Security/Fingerprint .............................................. > Browser Tests : Performance ....................................................... > Browser Tests : DNS/VPN/Proxy Leak ................................................ > Infos : Librefox Roadmap .......................................................... > Infos : Changelog ................................................................. > Infos : About .....................................................................
