misc (#1040)
* misc - cleanup of old release notation in comments: e.g. if it's not applicable to ESR78+ - same with default version info - simplify and save bytes on section 4700 - update 4500 header - and unify the message about using extensions as counterproductive - letterboxing - provide info on stepped ranged (and drop crap about FF67) - don't judge users who dislike seeing margins (I don't like them either, but I force my window to exact dimensions and stay there) - screenshots uploading was disabled in FF67+ : [67 release notes](https://www.mozilla.org/en-US/firefox/67.0/releasenotes/) - the pref is still there (default false) but so far I'm 99% sure this pref now does anything - I will add it to the scatchpad script if this change sticks * simplify 4500 RFP, see #1041 * update removed script * tidy readme, see #1045 - also put readme before releases * RIP FX Site Compat * clean out RFP Alts info: the information is redundant: it's already in the readme

|
||||
0. Consider using Tor Browser if it meets your needs or fits your threat model better
|
||||
* https://www.torproject.org/about/torusers.html.en
|
||||
1. READ the full README
|
||||
* https://github.com/arkenfox/user.js/blob/master/README.md
|
||||
2. READ this
|
||||
* https://github.com/arkenfox/user.js/wiki/1.3-Implementation
|
||||
3. If you skipped steps 1 and 2 above (shame on you), then here is the absolute minimum
|
||||
* Real time binary checks with Google services are disabled (0412)
|
||||
* You will still get prompts to update Firefox, but auto-installing them is disabled (0302a)
|
||||
* Some user data is erased on close (section 2800). Change this to suit your needs
|
||||
* EACH RELEASE check:
|
||||
- 4600s: reset prefs made redundant due to privacy.resistFingerprinting (RPF)
|
||||
or enable them as an alternative to RFP (or some of them for ESR users)
|
||||
- 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:
|
||||
1. Consider using Tor Browser if it meets your needs or fits your threat model better
|
||||
* https://www.torproject.org/about/torusers.html.en
|
||||
2. Required reading: Overview, Backing Up, Implementing, and Maintenance entries
|
||||
* https://github.com/arkenfox/user.js/wiki
|
||||
3. If you skipped step 2, return to step 2
|
||||
4. Make changes
|
||||
* There are often trade-offs and conflicts between security vs privacy vs anti-fingerprinting
|
||||
and these need to be balanced against functionality & convenience & breakage
|
||||
* Some site breakage and unintended consequences will happen. Everyone's experience will differ
|
||||
e.g. some user data is erased on close (section 2800), change this to suit your needs
|
||||
* While not 100% definitive, search for "[SETUP" tags
|
||||
* Take the wiki link in step 2 and read the Troubleshooting entry
|
||||
5. Some tag info
|
||||
[SETUP-SECURITY] it's one item, read it
|
||||
[SETUP-WEB] can cause some websites to break
|
||||
[SETUP-CHROME] changes how Firefox itself behaves (i.e. NOT directly website related)
|
||||
[SETUP-CHROME] changes how Firefox itself behaves (i.e. not directly website related)
|
||||
[SETUP-PERF] may impact performance
|
||||
[SETUP-HARDEN] maybe you should consider using the Tor Browser
|
||||
* [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)
|
||||
5. KEEP UP TO DATE: https://github.com/arkenfox/user.js/wiki#small_orange_diamond-maintenance

* RELEASES
|

|
||||
* Archive: https://github.com/arkenfox/user.js/releases
|
||||
* Use the correct release that matches your Firefox version
|
||||
* Each release

- run the prefsCleaner or reset deprecated prefs (9999s) and prefs made redundant by RFP (4600s)
|
||||
- re-enable section 4600 if you don't use RFP

This is FYI ONLY. These prefs are INSUFFICIENT(a) on their own, you need

iframes, headers, tcp/ip attributes, feature detection, and **many** more.
