[QUOTE="HarborFront, post: 895530, member: 55987"] Hello everyone. A few weeks ago I posted my [URL='https://www.reddit.com/r/privacy/comments/cuutwg/chromium_privacy_guide/'][B][U]Chromium Privacy Guide[/U][/B][/URL], and now I'm pleased to present a complementary guide for Firefox. I wasn't planning to write a guide for Firefox since there's literally tons of them out there, but I did feel quite ashamed that when someone asked me in that previous thread for my Firefox settings I didn't even have a proper user.js file to present. Everything I had was just a large blob of settings from my prefs.js file that hadn't been overhauled since the pre-quantum (Fx57) days. This ultimately led me down a journey for the last several weeks of going through each and every setting, cross referencing them with [URL='https://github.com/ghacksuserjs/ghacks-user.js/blob/master/user.js']ghacks user.js[/URL], organizing by common theme, documenting the key settings, removing any deprecated settings, repeated testing on Panopticlick and Browser Speedometer 2.0 for privacy and performance, and multi-day monitoring of about:networking to detect any possible unsolicited requests (and there were apparently a few that had snuck into Fx69). The end result I'm calling here is [B]Firefox Zero[/B], a user.js file that is tested for Fx69 and makes [I]zero[/I] network requests while running unless you specifically allow it.
