Besides turning off everything in Edit/Preferences/Advanced/Data Choices and browser.newtabpage.directory.ping

What should one change in Firefox settings to avoid sending extra info to Mozilla?

    @schroeder - ie6 - to ensure your browsing doesn't happen at all. :P – Deer Hunter Mar 26 '15 at 17:55
  • I went for the platform independent option, but, I also agree with you that I'd prefer Mozilla over Google for privacy. The question was about avoiding Mozilla, not privacy in general :) (checks overhead for a joke that might ben passing me by) – schroeder Mar 26 '15 at 18:16
  • Just telnet server.com 80, followed by GET /some/page HTTP/1.0 and two carriage returns. Parse the html/javascript in your head and respond accordingly. This way you can be sure to only send the relevant data. </joke> – ThoriumBR Mar 26 '15 at 20:06
  • The most secure browser is Tor, based off Mozilla. You can copy its settings. Tor uses the Tor network, a series of NSA-proof proxies. – noɥʇʎԀʎzɐɹƆ Jul 1 '16 at 19:25

It is unwise to post link-only answers, yet I'll point interested readers at https://github.com/pyllyukko/user.js. A metric tonne of security- and privacy-related settings are there, waiting to be implemented in your Firefoxes.

I also link to permanent webarchived version of the main script in case the repo gets deleted or lost: https://web.archive.org/web/20150413081702/https://github.com/pyllyukko/user.js/blob/master/user.js

Shameless self-promotion here: https://github.com/Hunter-Github/awesome-firefox as a repository of privacy-related links for FF.

There are a lot of settings and you will find a lot of collections of those.

Here's another shameless self-promotion, but i think it will really help you: https://ffprofile.com The site guides you through different settings and after deciding what you want to disable, you get a generated config-file and possibly some addons.

The project is linked there and everyone can and should suggest new settings on github. There is a whole category for stuff like this, called "firefox tracking" (in constrast to "website tracking").
