Outdated but helpful guide

Oh, one more

My Notes From ffprofile.com (with my opinions)

You can change your user-agent to more common than Firefox's default user-agent.

This website shows most common user-agents.

Or you can use this or this website.

But because of Firefox isn't Chromium-based, it can make you more unique (list of alternative tools) (because of some engine differences) instead less unique.

Templates

  1. Arkenfox (well-known)
  2. Pyllyukko
  3. Narsil's user.js (privacy focused not security)
  1. Vulpes
  2. Narsil's user.js for Pale Moon (for Pale Moon) (privacy focused not security)

Guides for Firefox Hardening

JArmandoG's Guide

Spyware Watchdog Mitigation Guide

My Notes From JArmandoG's Guide

These are some about:config options to consider changing after applied user.js settings.

  1. security.tls.version.min -> 3
  2. network.http.referrer.spoofSource -> true
  3. browser.display.use_document_fonts -> 0

My Notes From Spyware Watchdog Guide

You need to delete several default plugins in Firefox directory at /path/to/Firefox/browser/features

(I.e. /usr/lib/Firefox/browser/features/) that can violate privacy:

  • firefox@getpocket.com.xpi — Pocket
  • followonsearch@mozilla.com.xpi — Follow-On Search
  • activity-stream@mozilla.org.xpi — Activity Stream
  • screenshots@mozilla.org.xpi — Screenshots
  • onboarding@mozilla.org.xpi — Onboarding
  • formautofill@mozilla.org.xpi — Autofill
  • webcompat@mozilla.org.xpi — Web Compatibility Reporter

My Notes From Mullvad DNS Blog

In about:config make this: network.trr.mode -> 3

Or change the “DNS protection” preference in Settings.

It will force DNS over HTTPS every time you make a DNS request. (even if your DNS server doesn't respond)

My Notes From Unixsheikh

Look here

My Notes From Pedantic Software Blog

“For Google, I take this even further: if redirections are disabled (in Firefox's about:config, set accessibility.blockautorefresh to true; this used to be available in the normal config dialog, in the good old days), in addition to both CSS and javascript being disabled, then you'll see a simple page with the unmangled results links.”

Config Page

[chrome://geckoview/content/config.xhtml Open it…] Wiki

One More Thing

In about config, do this:

  • media.autoplay.enabled -> false
  • media.cache_readahead_limit = 0
  • media.cache_resume_threshold = 10
  • media.autoplay.blocking_policy = 1
  • media.autoplay.allow-muted -> false

This will disable autoplay and reduce video caching.

I don't know if it is necessary or not

about:config settings but haven't tried it yet (I temporarily switched to Chromium)

  • social.whitelist -> nothing
  • social.toast-notifications.enabled -> false
  • social.shareDirectory -> nothing
  • social.remote-install.enabled -> false
  • social.directories -> nothing
  • social.share.activationPanelEnabled -> false
  • browser.sessionstore.interval -> set it too high

ximatrix extension

ximatrix is a Firefox extension similar to uMatrix. ximatrix can block anything that uMatrix can. It's also can block inline things. You can look the code with this link. Or you can use paraMatrix which is fork of ximatrix.
