|
|
* "Singing, I love rock and pants. So put another dime in the jukebox, baby"
|
|
* authors: v52+ github | v51- www.ghacks.net
|
|
* url: https://github.com/ghacksuserjs/ghacks-user.js
|
|
|
|
* releases: These are end-of-stable-life-cycle legacy archives.
|
|
*Always* use the master branch user.js for a current up-to-date version.
|
|
url: https://github.com/ghacksuserjs/ghacks-user.js/releases
|
|
|
|
* 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 are disabled (section 0302's)
|
|
* Some user data is erased on close (section 2800), namely history (browsing, form, download)
|
|
* Cookies are denied by default (2701), we use site exceptions. This breaks extensions
|
|
that use IndexedDB, so you need to allow exceptions for those as well: see [1] below
|
|
[1] https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.7-Setting-Extension-Permission-Exceptions
|
|
* EACH RELEASE check:
|
|
- 4600s: reset prefs made redundant due to privacy.resistFingerprinting (RPF)
|
|
or enable them as an alternative to RFP or for ESR users
|
|
- 9999s: reset deprecated prefs in about:config or enable relevant section(s) for ESR
|
|
* 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
|
|
4. BACKUP your profile folder before implementing (and/or test in a new/cloned profile)
|
|
5. KEEP UP TO DATE: https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.5-Keeping-Up-To-Date

This section has security & tracking protection implications vs privacy concerns vs effectiveness
|

vs 3rd party 'censorship'. We DO NOT advocate no protection. If you disable Tracking Protection (TP)
|
|
and/or Safe Browsing (SB), then SECTION 0400 REQUIRES YOU HAVE uBLOCK ORIGIN INSTALLED.
|
|
|
|
Safe Browsing is designed to protect users from malicious sites. Tracking Protection is designed
|
|
to lessen the impact of third parties on websites to reduce tracking and to speed up your browsing.
|
|
These do rely on 3rd parties (Google for SB and Disconnect for TP), but many steps, which are
|
|
continually being improved, have been taken to preserve privacy. Disable at your own risk.

Shift+F4 to open the scratchpad, type window.resizeTo(1366,768), hit Ctrl+R to run. Test

/*** 4700: RFP (4500) ALTERNATIVES - NAVIGATOR / 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, date locale/formats, iframes, headers, resource://URIs,
|
|
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 4500)
|
|
which is already plugging leaks (see 1 above) the prefs below do not address
