cmd.exe has a command line length limit of 8192 characters. Abort if prefs.js contains strings that would get dropped while recreating the new prefs.js.
https://wiki.mozilla.org/Security:Renegotiation describes
> **the new default behaviour** that was introduced in experimental mozilla-central nightly versions on 2010-02-08
where the last step is
> - should the server (or a MITM) request **renegotiation**, Mozilla will terminate the connection with an error message
and then after talking about breakage ...
> The above defaults may break some client/server environments where a Server is still using old software and requires renegotiation.
mentions workarounds to reduce said breakage:
> In order to give such environments a way to keep using Firefox (et.al.) to connect to their vulnerable server infrastructure, the following preferences are available:
specifically talking about the first 2 prefs listed there, one allowing to specify a list of hosts "where renegotiation may be performed" and the 2nd one "completely disables the new protection mechanisms".
But both those prefs were removed in FF38, meaning that since then it's no longer possible to disable the default behaviour that is "should the server (or a MITM) request **renegotiation**, Mozilla will terminate the connection with an error message".
But all of this is about the **re**-negotiation part and not negotiation. And nowhere does it say "insecure" renegotiation, which, as I read it, means that FF will terminate the connection for any kind of **renegotiation**, safe or unsafe.
1201 controls the negotiation part:
> This pref controls the behaviour during the initial negotiation between client and server.
> If set to true, a Mozilla client will reject all connection attempts to servers that are still using the old SSL/TLS protocol and which might be vulnerable to the attack.
> Setting this preference to “true” is the only way to guarantee full protection against the attack.
I think "servers that are still using the old SSL/TLS protocol" actually means servers that **only** support the old protocols.
Servers still supporting those old protocols in addition to some new protocol versions should not be affected by this pref because FF will be able to negotiate to use one of the newer protocol versions.
Ergo lets fix the title and remove the line about renegotiation support because I think that's irrelevant.
ps. the sslpulse link is nice and I'd like to keep it somewhere but it doesn't really fit in 1201 IMO so I moved it to 1202.
- to avoid confusion with the setting tag, split the prefs into separate numbers, thus shove 2031->2031, reuse 2031
- remove the default value notation as Mozilla will roll out default change gradually to users
remember the new Coverage Telemetry shit? with a **hidden** opt-out pref? guess what, they are already collecting for 3 months ...
https://bugzilla.mozilla.org/show_bug.cgi?id=1487578 - **3 months ago**: "I see data coming in that looks reasonable"
guess what else ...
"It has also replaced the previous version that was there (from bug 1480194)" and oh, surprise surprise, 1480194 is ACCESS DENIED!
they're not just using private tickets to hide security critical information from potential hackers and blackhats, no they also use it to hide shady AF things. Things that they fully know are shady as fuck and that they absolutely know a lot of people would not like. There's simply no other reason why they'd do that
but wait, that's not all. If you think an opt-out pref that 99% of people wouldn't know about even if it showed up in about:config BUT ALSO HAPPENS TO BE HIDDEN is kind of questionable, well ... the system addon that they use for this shit apparently looked or still looks for `toolkit.telemetry.coverage.opt-out` [1] instead of `toolkit.coverage.opt-out` as their documentation [2] claims

It's time to opt out of all that shit for good. Disable system addon updates and kill it at the root
> In FF61 and lower, you will not get any System Add-on updates except when you update Firefox
on its own that's not true. You will get SA updates unless you disable app update checks + auto install. Let's just remove that as well.
* move 1260 to 122x
"disable or limit SHA-1 certificates" is about certs, not ciphers.
Because CERTS is 1st in the title I moved it to the 1st item there because it's arguably also the most important of the lot (and renumbered the rest)
We can also drop HSTS from the subgroup title because there's nothing HSTS left atm.
when argument `-l` is used, parse profiles.ini instead of just listing folders in the default profiles dir.
This allows to select profiles located outside of the default profiles directory and makes selection easier because it also shows the profile name (and selection is by number instead of having to copy-paste a path)
Pants said "We do not need to keep anything for ESR users. ESR users are on v60, and we have an archived 60 for them."
This isn't even affecting ESR60 but only older versions.
* removed, renamed or hidden in v63.0
- 0301a - do you want to add the `[NOTE] Firefox currently checks every 12 hrs ...` to `0302a` ? The problem is it also checks for updates every time you open/reload about:preferences and in Menu>Help>About Firefox regardless of when the last check was.
- 0513 - removed because follow-on-search is no longer a deletable system addon
- 2703 - do we just remove `3=for n days` or add a [NOTE] that value 3 was remove in FF63 or something?
- `browser.ctrlTab.recentlyUsedOrder` replaces `browser.ctrlTab.previews` but it now defaults to true. No need to list the new one under 5000 IMO
* Update user.js
* 1031 add more info
https://bugzilla.mozilla.org/show_bug.cgi?id=1453751#c28
* 0301a: remove update-check timing info
* 2703: add version deprecation for value 3
- pref removed in FF63 (https://bugzilla.mozilla.org/1476879)
- when we added it the default was false
- default is true since FF57
- it's only an UI thing
ergo we don't need to move it to 9999
* more infos
* add colons
not all EOL comments for defaults start with `// default` (23). The common string is `default:` (27 incl. these ones) with or without preceding or trailing spaces
I think there's no way to get rid of ^M but hopefully with `*.bat -text` in `.gitattributes` it shouldn't be a problem because git won't do any line conversion on check-in/out.
This way the raw link as well as the file within the zip download should be in proper MSDOS CRLF format, and git status shouldn't report the file as modified either. ***fingerscrossed!!***
