- explain pitfalls, add keyword tip, add setup tag
- given the searchbar is hidden by default in new FF installs, a lot of people could find this incredibly annoying (not being able to hit enter), including users who have changed their search engine - hence the setup tag
- these are not needed, you can view your cache in about:cache, or look at your `profile/cache2` folder (at least for portable Firefox), the remaining pref is enough to achieve the desired result
- browser.cache.disk.smart_size.first_run is set internally (for me it got automatically reset to modified false)
- the other two prefs are just more things for users to have deal with if they want to use disk cache
- Used setup-web since it relates to actual web pages, even though it doesn't break them
- Added the tag because it's an item that is likely to get attention / troubleshooting
- Added a warning tag to make the risk more apparent.
- Slight edit to the 2803 references
- 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
TAAR is extension recommendations in the "Add-ons Manager" (not sure how it's displayed)
CFR is extension recommendations as you browse the web, via a drop down panel
- description needs to stay changed from just cookies since it also clears site data
- keep the info about n days out of it, it's just messy (ESR users should be on version 60)
- get the values correct (I mixed them up earlier)
- fixup [setting] path
- leave in one (of two) extra [notes] I previously added
whatever we thought it may have done in the past, it doesn't do that now as far as we know. And it's not an issue since we allow extension update-CHECKs anyway.
regardless of this pref setting: the permissions.sqlite file will still be abused to store a flag for this for every single site you connect to (as third party?) - fun.
* clean up "Firefox Data Collection & Use"
- telemetry prefs to 330's
- Firefox Data Collection & Use prefs to 340's (but leave crash reports in 350s)
- move `app.shield.optoutstudies.enabled` to 330's - this is an internal pref which controls if you get the system addon
- make notes that `datareporting.healthreport.uploadEnabled` controls studies and ext recommendations
- split crash reports better to reflex the UI setting
`browser.urlbar.maxHistoricalSearchSuggestions` is default 0 is FF60 thru to FF66. It is also default 0 in ESR60.1 thru 60.5. (at least on Windows)
IDK if this has ever been used, maybe android, in which case it's probably useful?
The location bar dropdown cannot be disabled via prefs except with css, in which case the whole thing is hidden regardless of he above prefs. So there is no point in making any of them active. This is also in line with what we can achieve with relaxed and hardened tags / sticky issues - that is we can find a better balance, Shoulder surfers is a low risk, not even Tor Browser disables this stuff. People need to take responsibility and/or use common sense. Sure, we can leave em in for users to know about and enable if they want. End of story.
userChrome.css code is
```css
/* locationbar dropdown FF65+ */
#PopupAutoCompleteRichResult {display: none!important;}
```
might as well add it: needs t be taken into consideration when looking at the whole http2 thing. Will be interesting to see what Tor Browser does with it in ESR68
it's too hard to follow AS changes, and work out if disabling showing items (basic toggling of show/hide sections etc) actually stops downloading a localized local copy etc. For items we actually want to block, let the endpoint slaughter begin.
let's just coverage-our-ass on this one
While I don't mind telemetry (development needs meaningful feedback to better the product), and I trust the data is not PII, and/or anonymized into buckets etc (you can check this you know), and I understand this one needs to be outside the Telemetry pref in order to gather the one-time ping ... and I trust Mozilla's motives ... I'm starting to get a little annoyed at the non-stop incessant increasing telemetry bullshittery and ass-fuckery around sending data home, and the lengths some Mozilla devs will go to, to hide this info (hidden prefs, access denied tickets to hide discussion of what should be public, and even **not even adhering to their own documentation**).
I will also be killing as many Activity Stream endpoints as well - as long as they are in line with our js - pocket, snippets, onboarding etc. And I will add those from personal as inactive for end-users - eg cfr
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
[1] https://github.com/mozilla/one-off-system-add-ons/pull/131/files#diff-6e0cbf76986d04383ccb32a29ef27a7aR25
[2] https://hg.mozilla.org/mozilla-central/file/tip/toolkit/components/telemetry/docs/data/coverage-ping.rst#l32
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.
FYI, the https://www.privacytools.io/webrtc.html test in our wiki is 404, so I gave it a strikethru and added this one. This is also handy for 2001, but do we need to double up on it? We're only disabling WebRTC because of IP leaks, so I don't see the point in testing if WebRTC is disabled.
Session Restore cannot be disabled in Normal mode, it is also used internally. FYI: PB Mode does not use Session Restore. The description is still not 100%, as it refers to what is restored, not what is kept in the recovery.jsonlz4 (at least for tabs)
flipped true in FF54: https://bugzilla.mozilla.org/show_bug.cgi?id=1026804 but unsure when the pref itself was introduced. note: other timing prefs were always in 2400's see 4602: [2411] disable resource/navigation timing / 4603: [2412] disable timing attacks
it has zero to do with privacy etc, and in fact most users will only ever encounter it once (and check the box) when they first go to about:config, so it's not even useful as an override or a new profile IMO. This removes one of three numbers that don't have a section
TLS 1.0 and 1.1 are still secure. Sure, later versions are more secure, but 98% of the web is already upgraded - less than 2% of sites use < v1.2. So it's not very likely you would come across a site that requires it, but if you did, what's the point in breaking it. Mozilla and Chrome already have plans to deprecate TLS 1.0 & 1.1, and force that last 2% of sites.
TLS settings can be FP'ed without JS. By sticking with the defaults, I do not see any security issues, but an increase in potential anti-FPing. TBH, the chances of either (i.e being FP'ed with TLS as a entropy point, or being compromised due to TLS<1.2) are slim to non anyway.
Any arguments, please see @earthlng
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
FF61 introduced quite a few changes, including removing the ability to set a blank startpage in the UI, and a new Home options tab with unified Activity Stream (AS) defaults and dropdown options. Because the only way to stop AS on startup is to enforce a blank page (pref 0102), and setting this auto changes `home+newwindow` (0103) and `newtab` (0104) to a blank page, then we're just going to go ahead and enforce that on all of them.
For more info see the discussion in #426
Both deprecated in FF61, but we'll remove them from the user.js
- `services.blocklist.signing.enforced` is default true since FF50
- `browser.storageManager.enabled` only controls "Site Data" UI visibility
2732 was just enforcing default since at least FF52, and 2733 has never been used, was only there for info. Offline Cache or appCache (2730) is already behind a prompt (2731), and is already limited (in FF60+) to HTTPS (2730b).
Note: I am not 100% sure what happens with an app update. If this is divorced from that check now, you should be able to get FF updated without any system addons. We'll have to wait until 62 needs an update to test it. In the meantime I've edited the [NOTE]. I've also left this inactive (eg imagine if they pushed a critical update for formfill), so this is an end-user decision. Added to sticky to revisit this pref
I see no point in keeping this to enforce a default that FF itself doesn't use - see https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/User-Agent/Firefox
- "... is an optional compatibility token that some Gecko-based browsers may choose to incorporate, to achieve maximum compatibility with websites that expect Firefox"
The last one-off ESR cycle of 8 releases is now behind us, new algorithm for FF60+ is back to 7 releases per ESR numbering, starting at 60... 67... etc. Note: This does not do anything for Aurora or Nightly spoofing the next ESR early (but we have until Nightly 67 before this becomes a problem). The ticket 1418162 was meant to cover this but instead was just used for the new algorithm. There is currently no ticket for the Aurora/Nightly issue - but never fear, Pants is here!! It is not forgotten, and I have emails with Tom Ritter et al on it
AS is out of control. No master switch in FF60+, and in order to 100% sure nothing is collected locally (or external connections made), there are now some 28 prefs (including those coming in FF61). This is re-DICK-ulous. We're not going to bother tracking all that, let alone the labyrinth of code. All users are advised to just make sure they remove the XPI every time they update FF.
2711 is about web extension data and does not fit in the 2700s is all about websites' persistent data, i.e items that sanitizing and Storage Manager deal with. Dumping in 2600's which is getting a revamp later
* Options> and [settings]
While I'm at it, I'm changing the 21 instances of
- `[SETTING-56+]` to just `[SETTING]`
- `[SETTING-ESR]` to `[SETTING-ESR52]` because we'll leave those in until 62 (yes I know they may apply to earlier ESRs, but people should be upgraded). Thus no ambiguity with ESR60 vs ESR52 users for the overlap
This is so wrong: It is better to inform users that 3 **must** be used than rely on zero info as well as removing useful info on what the values do. All future issues with this will be directed to earthlng. Remove RFP info as RFP users should know this stuff if they turned it on. Non RFP users, who we told they can bypass it, will not have a reference to RFP now. Enforce will now be banned as a word because, "reasons".
add `browser.storageManager.enabled` back but enforce it as true - otherwise people may never pick up on the fact we dropped it and may never reset it, and never see their shiny new UI section. When it's deprecated, *then* we can remove it
pref will be removed, 99% sure it was just a pref used internally to hide it from stable during testing in beta/nightly - see https://bugzilla.mozilla.org/show_bug.cgi?id=1428306. Makes zero sense to hide this new UI section since we will be turning SM on anyway (the section is important for end users to exist and be working esp thru QuotaManager and Storage v2 changes etc).
note: picked up a leading space on 2206. Please double check for any errors or missed opportunities (I scanned it three times), 1221 is about the only one that's a bit messy I think
Note: I moved the (part`x`) bit to the end of the bugzilla from previous commit as I like the https* bit to all be in line = visually easier to parse IMO
This is a start to reducing section 2600 (which I renamed it to just miscellaneous). We can always revisit this new section and add to it down the track if required. Note: added a second ref [2] under 0703. Note: re-numbered & re-positioned deprecated prefs for SPDY
These are all at default values, no need to enforce. As for removing them, we're de-cluttering the section and these just aren't that important. Anyone who wants to play with tab ordering/focus/etc could probably use an extension (API's?) and/or easily find these and look them up
geolocation blocking via RFP will be removed (see https://bugzilla.mozilla.org/show_bug.cgi?id=1441295), and since either way you look at it (those who use RFP or not) the user.js blocks geo, so we might as well move this stuff back to section 0200
1376865 was back ported to 59, so canvas prompt fatigue will be reduced. Note: the default for non-prompts is the same as if you clicked "Don't Allow" - i.e it serves up a 10x10px white square
Cleaning up the UA spoof stuff in the sticky, as a ticket was just closed (52 is now a temporary hard-coded value: 1418672 - I guess they're running out of time), so also cleaning up the info, and consistent layout
Two issues: The code to determine the ESR number is out of whack (by one) since the next ESR is 60. 59 stable is almost here. So they have decided to hard-code the value as 52, for now. The second issue is that Aurora/Nightly are ahead of stable/ESR and can thus unmask themselves as Aurora/Nightly. The hard-coded value for now also solves this.
If you follow the sticky for RFP, you will see there is a ticket for using the update channel information (eg stable, beta, dev, nightly etc) to determine when and how calculate the version spoof in future, and they'll also rejig the numbering algorithm to account for ESR being out by one. These are tickets https://bugzilla.mozilla.org/show_bug.cgi?id=1418162 and https://bugzilla.mozilla.org/show_bug.cgi?id=1428111
