|
|
* https://www.torproject.org/about/torusers.html.en
|
|
|
|
1. READ the full README
|
|
|
|
2. Required reading: Overview, Backing Up, Implementing, and Maintenance entries
|
|
|
|
* https://github.com/ghacksuserjs/ghacks-user.js/blob/master/README.md
|
|
|
|
* https://github.com/arkenfox/user.js/wiki
|
|
|
|
2. READ this
|
|
|
|
3. If you skipped step 2, return to step 2
|
|
|
|
* https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.3-Implementation
|
|
|
|
4. Make changes
|
|
|
|
3. If you skipped steps 1 and 2 above (shame on you), then here is the absolute minimum
|
|
|
|
* There are often trade-offs and conflicts between security vs privacy vs anti-fingerprinting
|
|
|
|
* Real time binary checks with Google services are disabled (0412)
|
|
|
|
and these need to be balanced against functionality & convenience & breakage
|
|
|
|
* You will still get prompts to update Firefox, but auto-installing them is disabled (0302a)
|
|
|
|
* Some site breakage and unintended consequences will happen. Everyone's experience will differ
|
|
|
|
* Some user data is erased on close (section 2800). Change this to suit your needs
|
|
|
|
e.g. some user data is erased on close (section 2800), change this to suit your needs
|
|
|
|
* EACH RELEASE check:
|
|
|
|
* While not 100% definitive, search for "[SETUP" tags
|
|
|
|
- 4600s: reset prefs made redundant due to privacy.resistFingerprinting (RPF)
|
|
|
|
* Take the wiki link in step 2 and read the Troubleshooting entry
|
|
|
|
or enable them as an alternative to RFP (or some of them for ESR users)
|
|
|
|
5. Some tag info
|
|
|
|
- 9999s: reset deprecated prefs in about:config or enable the relevant section 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 changes, and to troubleshoot at times (choose wisely, there is always a trade-off).
|
|
|
|
|
|
|
|
While not 100% definitive, search for "[SETUP". If required, add each pref to your overrides section at
|
|
|
|
|
|
|
|
default values (or comment them out and reset them in about:config). Here are the main ones:
|
|
|
|
|
|
|
|
[SETUP-SECURITY] it's one item, read it

[WARNING] used sparingly, heed them
|
|
|
|
* [WARNING] tags are extra special and used sparingly, so heed them
|
|
|
|
|
|
|
|
4. BACKUP your profile folder before implementing (and/or test in a new/cloned profile)
|
|
|
|
* RELEASES: https://github.com/arkenfox/user.js/releases
|
|
|
|
5. KEEP UP TO DATE: https://github.com/ghacksuserjs/ghacks-user.js/wiki#small_orange_diamond-maintenance
|
|
|
|
|
|
|
|
|
|
|
|
* It is best to use the arkenfox release that is optimized for and matches your Firefox version
|
|
|
|
|
|
|
|
* EVERYONE: each release
|
|
|
|
|
|
|
|
- run prefsCleaner or reset deprecated prefs (9999s) and prefs made redundant by RPF (4600s)
|
|
|
|
|
|
|
|
- re-enable section 4600 if you don't use RFP
|
|
|
|
|
|
|
|
ESR78
|
|
|
|
|
|
|
|
- If you are not using arkenfox v78... (not a definitive list)
|
|
|
|
|
|
|
|
- 1401: document fonts is inactive as it is now covered by RFP in FF80+
|
|
|
|
|
|
|
|
- 4600: some prefs may apply even if you use RFP (currently none apply as of FF84)
|
|
|
|
|
|
|
|
- 9999: switch the appropriate deprecated section(s) back on
