* README:

|
|
|
2021-08-16 06:02:15 +02:00
|
|
|
1. Consider using Tor Browser if it meets your needs or fits your threat model
|
2021-12-04 11:23:59 +01:00
|
|
|
* https://2019.www.torproject.org/about/torusers.html
|
2022-02-13 12:15:00 +01:00
|
|
|
2. Read the entire wiki
|
2020-10-20 13:58:20 +02:00
|
|
|
* https://github.com/arkenfox/user.js/wiki
|
|
|
|
|
3. If you skipped step 2, return to step 2
|
2022-02-13 12:15:00 +01:00
|
|
|
4. Make changes in a user-overrides.js
|
2021-11-22 19:15:53 +01:00
|
|
|
* There are often trade-offs and conflicts between security vs privacy vs anti-tracking
|
2020-10-20 13:58:20 +02:00
|
|
|
and these need to be balanced against functionality & convenience & breakage
|
|
|
|
|
* Some site breakage and unintended consequences will happen. Everyone's experience will differ
|
2021-11-22 06:40:49 +01:00
|
|
|
e.g. some user data is erased on exit (section 2800), change this to suit your needs
|
2020-10-20 13:58:20 +02:00
|
|
|
* While not 100% definitive, search for "[SETUP" tags
|
2021-08-23 08:04:19 +02:00
|
|
|
e.g. third party images/videos not loading on some sites? check 1601
|
2020-10-20 13:58:20 +02:00
|
|
|
5. Some tag info
|
2019-04-29 07:27:16 +02:00
|
|
|
[SETUP-SECURITY] it's one item, read it
|
2018-12-04 06:36:03 +01:00
|
|
|
[SETUP-WEB] can cause some websites to break
|
2020-10-20 13:58:20 +02:00
|
|
|
[SETUP-CHROME] changes how Firefox itself behaves (i.e. not directly website related)
|
2020-12-25 17:06:32 +01:00
|
|
|
6. Override Recipes: https://github.com/arkenfox/user.js/issues/1080

|
|
|
2020-11-11 17:12:57 +01:00
|
|
|
* It is best to use the arkenfox release that is optimized for and matches your Firefox version
|
|
|
|
|
* EVERYONE: each release

cleanup continued, #1239
More minor tweaks to come. This isn't final
- 0102: ambiguous that the clearing was related to PB mode
- 0900s:
- get rid of 0901, it has no pref, stick link in header
- 0905: values on multi-lines use spaces = more readable
- 1000s:
- rename as disk avoidance and remove sub-section headers
- remove the outdated section header
- 4001: it will never be perfected, it's doing it's job
- 5500s: optional hardening
- legit security measures, but commonality in caveats, so I made them a separate section
- this flips graphite, asm.js and wasm from active to inactive: these are overkill: exhibit A: hundreds of millions of Firefox users
- e.g. graphite and wasm are enabled on Tor Browser
- new CVE keyword links
- 7000s: don't bother - two more items added
- 5000s: optional opsec and cleanout 0800s header
- re-number
- 0900s, 1000s, 1400s, 2400s

cleanup continued, #1239
More minor tweaks to come. This isn't final
- 0102: ambiguous that the clearing was related to PB mode
- 0900s:
- get rid of 0901, it has no pref, stick link in header
- 0905: values on multi-lines use spaces = more readable
- 1000s:
- rename as disk avoidance and remove sub-section headers
- remove the outdated section header
- 4001: it will never be perfected, it's doing it's job
- 5500s: optional hardening
- legit security measures, but commonality in caveats, so I made them a separate section
- this flips graphite, asm.js and wasm from active to inactive: these are overkill: exhibit A: hundreds of millions of Firefox users
- e.g. graphite and wasm are enabled on Tor Browser
- new CVE keyword links
- 7000s: don't bother - two more items added
- 5000s: optional opsec and cleanout 0800s header
- re-number
- 0900s, 1000s, 1400s, 2400s
PS: I need a new parrot: "9000 syntax error: I ran out of parrots"

turn ETP on everywhere
It literally cannot hurt [1], and makes it easier for users to use custom mode with TCP/dFPI. Turning on socialtracking helps gain parity with strict mode
[1] gorhill: https://old.reddit.com/r/firefox/comments/l7xetb/network_priority_for_firefoxs_enhanced_tracking/gl9rn9n/
> All extensions and ETP work in parallel, they all inspect network requests and all make the decision to block or not, hence if they all decide to block, they will all report that they block something. ETP is a bit different than normal extension in that it will give precedence to an extension trying to redirect to a local resource, this ensures ETP works harmoniously with normal extensions.
>
> Once something is not blocked, it then goes through a DNS query, and the browser waits for the response.
>
> I will add examples of how ETP + multiple blocker extensions work together when dealing with a network request; let's say "A" and "B" are two different blockers:
>
> - ETP=block, A=allow, B=allow: result=block
> - ETP=allow, A=block, B=allow: result=block
> - ETP=allow, A=allow, B=redirect: result=redirect
> - ETP=allow, A=block, B=redirect: result=block
> - ETP=block, A=allow, B=redirect: result=redirect
>
> So as you can see, ETP is a bit different than a normal extension in that it won't prevent redirection from happening if ever a network request is redirected by one of the normal extension.
