1. READ the full README at github

|
2. READ the full README at github
|
|
|
|
3. If you skipped steps 1 and 2 above (shame on you), then here is the absolute minimum
|
|
|
|
* The settings below will turn off Tracking Protection, Safe Browsing and Auto Updates
|
|
|
|
You need to read, understand, and decide about these. Don't leave yourself less secure
|
2017-04-17 13:34:44 +02:00
|
|
|
* Some user data is erased (section 2800), namely history (browsing, form, download)
|
2017-02-27 12:04:23 +01:00
|
|
|
* Site breakage WILL happen
|
|
|
|
- There are often trade-offs and conflicts between Security vs Privacy vs Anti-Fingerprinting
|
|
|
|
and these need to be balanced against Functionality & Convenience & Breakage
|
|
|
|
* You will need to make a few changes to suit your own needs
|
|
|
|
- Search this file for the "[SETUP]" tag to find SOME common items you could check
|
|
|
|
before using to avoid unexpected surprises
|
|
|
|
- Search this file for the "[WARNING]" tag to troubleshoot or prevent SOME common issues

/*** 0400: QUIET FOX [PART 2] [WARNING] [SETUP]
|
|
|
|
This section has security & tracking protection implications vs privacy concerns vs effectiveness.
|
|
|
|
These settings, WITH EXTENSIONS, are geared up to make Firefox "quiet", private and effective.
|
|
|
|
We DO NOT advocate no protection, so use something with more scope, such as uBlock Origin.
|
|
|
|
|
|
|
|
This entire section is rather contentious. Safebrowsing (SB) is designed to protect
|
|
|
|
users from malicious sites. Tracking protection (TP) is designed to lessen the impact of third
|
2017-02-17 06:25:30 +01:00
|
|
|
parties on websites to reduce tracking and to speed up your browsing experience. These are
|
|
|
|
both very good features provided by Mozilla. They do rely on third parties: Google for
|
|
|
|
safebrowsing and Disconnect for tracking protection (someone has to provide the information).
|
|
|
|
Additionally, SSL Error Reporting helps makes the internet more secure for everyone.
|
2017-02-27 12:04:23 +01:00
|
|
|
|
|
|
|
If you do not understand the ramifications of disabling SB and TP, then it is advised that
|
2017-02-17 06:25:30 +01:00
|
|
|
you enable them by commenting out the preferences and saving the changes, and then in
|
2017-02-27 12:04:23 +01:00
|
|
|
about:config find each entry and right-click and reset the preference's value.

If you are in a private environment (no unwanted eyeballs) and your device is private
|
|
|
|
(restricted access), and the device is secure when unattended (locked, encrypted, forensic
|
|
|
|
hardened), then items 0850 and above can be relaxed in return for more convenience and
|
|
|
|
functionality. Likewise, you may want to check the items cleared on shutdown in section 2800.

|
|
|
[NOTE] The urlbar is also commonly referred to as the location bar and address bar

/*** 1200: HTTPS ( SSL/TLS / OCSP / CERTS / HSTS / HPKP / CIPHERS )
|

|
|
Note that your cipher and other settings can be used server side as a fingerprint attack
|
|
|
|
vector, see [1] (It's quite technical but the first part is easy to understand
|
|
|
|
and you can stop reading when you reach the second section titled "Enter Bro")
|
|
|
|
|
|
|
|
Option 1: Use our settings to tighten up encryption options. It *is* a fingerprinting attack
|
|
|
|
vector, and we certainly do want to reduce any attack surface, but this is not how
|
|
|
|
you *DEFEAT* fingerprinting - to do that you need large numbers to buy into the same
|
|
|
|
enforced browser-wide settings (such as TBB), and/or you use OpSec.
|
|
|
|
Option 2: Use Firefox defaults for the 1260's items (item 1260 default for SHA-1, is local only
|
|
|
|
anyway). There is nothing *weak* about Firefox's defaults, but Mozilla (and other
|
|
|
|
browsers) will always lag for fear of breakage and upset end-users

/*** 1600: HEADERS / REFERERS [SETUP]
|
2017-03-07 16:24:22 +01:00
|
|
|
Except for DNT (Do Not Track), referers are best controlled by an extension.
|
2017-03-08 16:43:13 +01:00
|
|
|
It is important to realize that it is *cross domain* referers that need
|
|
|
|
controlling, and this is best handled by EITHER 1603 or 1604, not both.
|
2017-03-16 16:22:45 +01:00
|
|
|
|
2017-03-08 16:43:13 +01:00
|
|
|
Option 1: Recommended: Use an extension to block all referers, and then whitelist
|
|
|
|
sites on a granular, per domain level.
|
2017-03-08 18:15:43 +01:00
|
|
|
Option 2: As per the original settings below: Set XOriginPolicy (1603) to 1 (less breakage)
|
2017-03-08 16:43:13 +01:00
|
|
|
or 2 (more breakage) and leave XOriginTrimmingPolicy (1604) at default 0
|
|
|
|
Option 3: Set XOriginPolicy (1603) to default 0 and set XOriginTrimmingPolicy (1604) to 2

/*** 2697: USER AGENT (UA) SPOOFING
|
|
|
|
Spoofing your UA to *LOWER* entropy *does* *not* *work*. It may even cause site breakage
|
|
|
|
depending on your values. Even if you spoof, like TBB (Tor Browser Bundle) does, as the
|
2017-02-27 12:04:23 +01:00
|
|
|
latest ESR, it still *does* *not* *work*. There are two main reasons for this.
|
2017-02-23 16:34:52 +01:00
|
|
|
1. Many of the components that make up your UA can be derived by other means. And when
|
|
|
|
those values differ, you provide more bits and raise entropy. Examples of leaks include
|
|
|
|
navigator objects, resource://URIs, <isindex> locale, feature detection and more.
|
2017-02-27 12:04:23 +01:00
|
|
|
2. You are not in a controlled set of significant numbers, where the values are enforced
|
2017-02-23 16:34:52 +01:00
|
|
|
by default. It works for TBB because for TBB, the spoofed values ARE their default.
|
|
|
|
* We do not recommend UA spoofing yourself, leave it to privacy.resistFingerprinting (see 2699)
|
|
|
|
* Values below are for example only based on the current ESR/TBB at the time of writing
