|
|
|
|
|
|
|
|
* README:
|
|
|
|
|
|
|
|
|
|
1. READ the full README
|
|
|
|
|
* https://github.com/ghacksuserjs/ghacks-user.js/blob/master/README.md
|
|
|
|
|
2. READ this
|
|
|
|
|
* https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.3-Implementation
|
|
|
|
|
3. If you skipped steps 1 and 2 above (shame on you), then here is the absolute minimum
|
|
|
|
|
* Auto-installing updates for Firefox and extensions/addon-ons are disabled (section 0302's)
|
2017-07-18 13:35:00 -04:00
|
|
|
* Some user data is erased on close (section 2800), namely history (browsing, form, download)
|
2017-07-14 10:20:40 -04:00
|
|
|
* Cookies (and thus logins) are denied by default (2701). Use site exceptions or an extension
|
2017-06-17 03:13:14 -04:00
|
|
|
* 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
|
2017-07-15 03:37:27 -04:00
|
|
|
4. BACKUP your profile folder before implementing (and/or test in a new/cloned profile)
|
2017-07-14 10:20:40 -04:00
|
|
|
5. KEEP UP TO DATE: https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.5-Keeping-Up-To-Date

data being sent to Google from all other settings such as using local blocklists/whitelists and

updating those lists. There are NO privacy issues here. *IF* required, a full url is never sent

Google also swear it is anonymized and only used to flag malicious sites/activity. Firefox

also takes measures such as striping out identifying parameters and storing safe browsing

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

sites on a granular, per domain level.

Option 2: As per the original settings below: Set XOriginPolicy (1603) to 1 (less breakage)

|
|
|
or 2 (more breakage) and leave XOriginTrimmingPolicy (1604) at default 0

|
|
|
|
|
A worker is a JS "background task" running in a global context, i.e it is different from
|
|
|
|
|
the current window. Workers can spawn new workers (must be the same origin & scheme),
|
|
|
|
|
including service and shared workers. Shared workers can be utilized by multiple scripts
|
|
|
|
|
and communicate between browsing contexts (windows/tabs/iframes) and can even control your
|
|
|
|
|
cache. Push and web notifications require service workers, which in turn require workers.
|
|
|
|
|
|
|
|
|
|
[WARNING] Disabling workers *will* break sites (eg Google Street View, Twitter).
|
|
|
|
|
It is recommended that you use a separate profile for these sorts of sites.

/*** 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
|
|
|
|
|
latest ESR, it still *does* *not* *work*. There are two main reasons for this.
|
|
|
|
|
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.
|
|
|
|
|
2. You are not in a controlled set of significant numbers, where the values are enforced
|
|
|
|
|
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
