In case you're using Firefox on mobile - so myself and like four others - disabling Firefox' new Facebook data collection feature is quite a bit harder than on desktop, but it can be done:

1. Go to chrome://geckoview/content/config.xhtml
2. Use the search field to find the entry for aboutConfig and enable it
3. Go to about:config
4. Search for dom.private-attribution.submission.enabled and set it to false

Done. This only works on Android, because Firefox on iOS is just a Safari skin.

@thomholwerda does it also work for all 2 people who use firefox on ios
Eniko | Kitsune Tails out now!

@thomholwerda i use firefox on mobile because i need ublock origin >_> so thank you

Itanium Thom

@eniko Yeah I use Firefox on Android for uBlock when I'm not at home (where we have a Pi-Hole to block all ads on our entire network), and because I use Firefox on desktop, and use the tab sharing feature a lot.

unhinged and unafraid

@thomholwerda @eniko samesies, it's the tab sharing feature that keeps me on Firefox tbh.

Liam Ward

@dorian @thomholwerda @eniko so there are the 3 of you and I've just done it too so that's 100% of the FF android user base done now

Erik

@dorian
Btw, firefox forks (at least Mull and Librewolf) can also connect to your Firefox account and use it for sharing between devices.

Paul :archlinux: 🐧

@thomholwerda @eniko I have my phone rooted and I use AdAway to block all ads.
The rest of my family uses AdGuard DNSs, have tried any of these?

Natasha

@thomholwerda FYI, the first setting is under "general.aboutConfig.enable" on Firefox for Android. So search for "aboutConfig" not "about:config".

Itanium Thom

@natarasee Whoops, totally right. Good catch, thank you! Fixed the post.

kaybeeque

@thomholwerda @natarasee ah, thanks very much for the clarification. I hadn't picked up that there were two separate toggles to check (my general one was already set to False).

Now done 👍

Dibs

@thomholwerda I can't even open chrome://geckoview/content/config.xhtml - it just assumes I meant to enter an https:// address and f's it up

Alexander The 1st

@dtwx @thomholwerda If you paste it in, you have to manually add the prefix of `chrome://` again.

At least in non-In Private Mode, that was necessary - it seemed to paste in fine in In Private Mode, though it... apparently kept those options around outside of In Private Mode based on checking in non-In Private Mode.

jmorahan

@dtwx @thomholwerda that happened to me too when I tried to copy and paste, but typing it in seems to work

MeaTLoTioN

@thomholwerda It's ghastly how much telemetry people keep putting in stuff these days, it is beyond a joke now.

Telnet BBS for the win! 😅

TudbuT :v_bi:

@thomholwerda i use it! and i even bullied my dad into also doing that!

also wth facebook?!

Malaĉa maman chat 🌟

@TudbuT @thomholwerda yeah not sure what’s would be the link with Facebook?

Malaĉa maman chat 🌟

@thomholwerda @TudbuT Mozilla is really digging its own grave, isn’t it.

Tunguska

@Matheo_bis

I'm rooting for Servo @servo
myself. It's a ways from an end-user-ready browser at this point, but looks to be getting lots of active development, under the stewardship of The Linux Foundation, and I haven't come across any indication of gross toxicity among the project leadership.

@thomholwerda @melunaka @TudbuT

zyxhere💭

@tunguska @Matheo_bis @servo @thomholwerda @melunaka @TudbuT but servo's only the webengine you need to build a browser around it and who would do that and who can gaurantee that they won't add telemetry to it 😿

chocobo13ζ

@thomholwerda
I guess with the news that Switzerland will be funding open source tools for stuff their government employees use, we may be seeing a new browser coming from a team mostly based there, if we are lucky. Depends on whether Firefox or Chromium are considered "good enough" for their purposes
@melunaka @TudbuT

Flippin' 'eck, Tucker!

@thomholwerda Wow. Even on the supposedly highly privacy-conscious "Firefox Focus" that option was still set to True.

#Firefox #FirefoxFocus

sophiæ disœder :verified_woozy:

@thomholwerda@exquisite.social bigger wtf is they hid about:config on mobile?? i remember just being able to go to it..

Renarde

@thomholwerda
Doesn't seems to exist on Fennec-fdroid, hope the maintainer set it to false when they rebase on Firefox.

Paul :archlinux: 🐧

@Lana @thomholwerda do you feel Fennec slower than FF?
Can you use add-ons like Ublock?

zyxhere💭

@Lana @thomholwerda because fennec is still on v127 this feature is introduced in v128

dataf#z̧̽̿̋̊̊̃ͨ̎̈́҉z̎̃ͦ̍͋͛̆ͯ͜

@thomholwerda thank you so much ive just looked for it in the settings but couldn't find it so figured maybe they didn't implement it on phones. putting this opt out option out of sight is really a shame.

Paul :archlinux: 🐧

@datafuzz @thomholwerda try to search for aboutConfig without the colon

Jor ☝️😐 (en pause ⏸️ des RS)

@thomholwerda Thank you for the tip.

(But it is just incredible that we have to go through all that just to disable something that should at least have been an opt-in, or shouldn’t have existed at all. 😬)

draconicrose

@jor it's also weird since on desktop it just has a toggle in settings.

qrazi

@thomholwerda One of the others thanks you sir!

Ewen Bell

@thomholwerda

Thankyou! That's not an easy stone to turn.

Firefox on Android
Dave MacFarlane

@thomholwerda@exquisite.social thank you! I've been trying to figure out how to do it and assumed it just hasn't made it to mobile yet.

Ángela Stella Matutina

@thomholwerda

Heh, a lot of us started using only Firefox somewhere along the way. Thank you!

Itanium Thom

@angelastella Same! Any other browser is just wrong for my usage pattern. I'm worried about the future of Firefox. 😐

Ángela Stella Matutina

@thomholwerda

Me too. I'm waiting for some viable third option to mature. (Contributing code to a modern browser it's way above my pay grade.)

StreetDogg

@thomholwerda So this is what the Mozilla people mean when they say "it's fine, it's opt-out!" ... o_0

o ifrit

@thomholwerda You also can swing to Mull (or other nice Firefox fork) 😜
@hipolito

O/A Randomhose

@thomholwerda and, just asking to anyone, what about duck duck mobile browser? Does it worth it?

nano shinonome 🎄🐴

@thomholwerda you can also just jump straight to the private attribution option and turn it off in the chrome:// url

Simon Brooke

@thomholwerda Done. But pretty shit that `false` is not the default. Really unimpressed, @mozilla

Privacy intrusion by stealth: the moral equivalent of peeking through people's bathroom windows.

Magnus Ahltorp

@simon_brooke @thomholwerda @mozilla But don’t worry, we’re the ones peeking through your bathroom window, and we will only make sketches of what we see in our sketchbook. We will write down your name or address on the opposite page, so everything will be anonymous unless someone steals the book.

Yeah, and this will not make any of the people across the street with binoculars go away. We will ask them nicely to buy copies from our sketchbook, though.

Hubert Figuière

@thomholwerda and in that case there is an option in Advanced for Safari to opt out (if it applied)

Sietske Boer-van Vugt

@thomholwerda Thanks! do I need to turn the aboutConfig setting back to false after doing this?

Deborah Edwards-Oñoro

@bumblebeedc @thomholwerda I had the same question. I toggled it back to false after making changes.

Xerz! :blobcathearttrans:

@thomholwerda not an issue on Fennec F-Droid! but thanks for sharing, I know of people who will need it…

Jaime Herazo

@thomholwerda
Do we know if this shit is in Firefox Focus?

Edit: Answering myself, it IS on Firefox Focus, the supposedly super-private edition of Firefox, for fuck's sakes... 🤦

Condalmo.

@thomholwerda Can you link us to directions on doing it on desktop Firefox?

Condalmo.

@thomholwerda Also, I don't understand - Chrome? Why is the direction to enter "chrome" in a browser that isn't Chrome?

guenther

@condalmo

The term "chrome" historically refers to the UI elements of the browser itself, i.e. everything other than the websites it displays. It's been in use since long before Google started making a browser and called it Chrome, but it's been confusing people since then.

See the second bullet point under "Computing" in this article:
en.m.wikipedia.org/wiki/Chrome

@thomholwerda

Bernard

@thomholwerda couldn't get the about:config to work. Until I found that it's only available in Firefox Beta, not in the official released version: droidwin.com/cannot-access-abo

JProl 🌍🎶💾🆓🐦

@SchepBernard @thomholwerda if you follow OP's steps you can enable about:config in Firefox (not beta nor nightly)

Deus

@thomholwerda Or just use Mull.

This is a privacy oriented and deblobbed web browser based on Mozilla technology. It enables many features upstreamed by the Tor Uplift project using preferences from the arkenfox-user.js project. It is recommended to install 'uBlock Origin'.

Arlen Moller

@thomholwerda thank you. I’m looking for a new browser on iOS, any suggestions?

AE4WX

@thomholwerda I can't open the config file. Bye Firefox.

draeath

@thomholwerda holy hell thank you for showing how to enable about:config all on it's own!

I've wanted that for years now.

flw

@thomholwerda Thank you! It worked (was necessary) for Firefox Klar as well.

Paul :archlinux: 🐧

@thomholwerda interesting. I would've thought that that wasn't active or that it didn't even exist!

Thanks for the tip.

rick
@thomholwerda wait what? its there too? and so hidden?!
mccraigmccraig

@thomholwerda another possibility: use the Firefox-beta app, which has about:config enabled by default

Claire :verifiedbi::hatched_trans_egg:

@thomholwerda@exquisite.social
1. i'm glad that you can use about:config on stable
2. why in the fuck is the method to enable about:config so obscure?

Andreas K

@thomholwerda
Considering that my malware detector notifies me about dangerous links when I visit many news sites without an ad blocker, the solution is simpler. Adblock.

Paul :archlinux: 🐧

@thomholwerda I've just found that the submission option is also enabled on the desktop.
Damn!

buddhaha

@thomholwerda that is only a temporary solution. The long term solution is:
1. Uninstall Firefox
2. Download & install Mull or Fennec F-Droid
3. ?
4. Profit

i gave this exact same advice to how to deactivate it on the desktop but instead recommending Librewolf

Tom Rini

@thomholwerda Thanks! I, sigh, thought it was too good to be true to assume it was just part of the other visible ad related toggle in preferences.

Pseudo Nym

@thomholwerda

Thank you.

I was wondering where they stashed the fiddly settings on mobile. Bookmarking

gz

@thomholwerda
While this is useful - thank you - it's a bit confusing as words run into each other, making the instructions unclear.

bebatjof

@thomholwerda Thanks for posting this. I don't understand step 3.

I went to the thing of step 1, found the thing of step 2 and clicked "toggle" to change it. In the same search field, I found the thing of step 4 as well, and changed it to false.

Can someone confirm that I did this okay?

(I have no idea what these things are, and I hate that they make it nearly impossible for non-tech people to have privacy.)

madmax

@bebatjof @thomholwerda Yup, you did everything that was needed to be done. Firefox android (stable) disabled about:config altogether which was enabled in step1 and you can use about:config or the thing from step1 to do the same. I think step1 has more advanced settings and about:config doesn't have those, that's the only difference I could find. Honestly, I am tired of changing this and that option as they continue to do these things and refuses to make it easy to disable them.

Karl

@thomholwerda Wow, what a user-hostile set of hoops to jump through.

Florian Judith

@thomholwerda thanks for the tip ! I may be the fifth person to use it !

cc @tut_tuuut

CatSalad🐈🥗 (D.Burch) :blobcatrainbow:

@thomholwerda Since Firefox sometimes will not let you paste the chrome:// on Android (wtf), just type that prefix manually.

Force of Habit

@catsalad @thomholwerda I'm just wondering. Does Focus use encrypted DNS by default or would a VPN block it?

David

@thomholwerda Cant find the private-attribution in Firefox 127.0.2 (Build #2016028743) 🧐

Ray Glittersoft

@thomholwerda@exquisite.social Thanks mate, I was wondering about this ​:raritywink:​

truh

@thomholwerda Firefox mobile strips the chrome:// scheme of the URL when you paste it into the bar, so it ends up being interpreted as a search query. This can be fixed by typing in chrome:// at the beginning of the URL before pressing enter.

zyxhere💭

@thomholwerda hopefully @fdroidorg 's fennec (firefox with telemetry and proprietary stuff removed) autormatically does this

Crafty

@thomholwerda ya know what, fuck it, I'll just uninstall it. It's by far the worst mobile browser I've ever used anyway 😂

Gustavo

@thomholwerda Is that already disabled in Iceraven and Mull, right?

lemgandi

@thomholwerda Thx! Worked like a charm. I haven't had a FB login since 2014 or so. Are they still tracking me?

Steve Popovich

@thomholwerda done, thanks! These companies are so sneaky these days about grabbing our data.

revres

@thomholwerda do i need to repeat this everytime firefox for android updates?

madmax

@Paladin this is something co-authored by meta and has nothing to do with specifically using Facebook. In short, if you like privacy then disabling it is a good idea.

Paladin :verified: :ak:

@pikachu_sensei WTF? Firefox usually is is good for privacy. Thank you for the tip.

accessibility.blockautorefresh = True

cephie

@thomholwerda
Noteworthy that this /is/ necessary on Firefox Focus/Klar, too

mcc

@thomholwerda Hold on, has it been specifically confirmed that this feature is *active* in Firefox mobile? I heard reports that the checkbox was in nightly but not shipping 128 and assumed that meant the feature isn't in shipping 128 either, but maybe I gave Firefox too much credit.

mcc

@thomholwerda Also, just to note, there's a comment in your thread saying that Firefox for iOS doesn't have this problem because it uses Webkit, not Firefox's engine (I can't reply because I guess fosstodon and m.s don't talk). Anyone assuming this should be aware that Apple has had this same feature since 2021 apple.com/legal/privacy/data/e And this *is* in WebKit, you can find it in the source code. It is unknown (to me) if the feature activates in apps embedding WebKit, or if it can be turned off.

Don Marti

@mcc @thomholwerda fwiw the instructions on that page don't mention that it's buried under "Advanced" in the iOS settings and on the "Advanced" tab in Mac OS

Don Marti

@mcc @thomholwerda it seems like it should be possible to send fake conversion events from a surrogate script that gets pulled in by a uBlock Origin rule...anyone got an example of a script actually doing this on a live site?

mcc

@dmarti @thomholwerda Maybe a good first step would be a browser extension that just identifies whether "please phone home later" codes of Google, Apple, or Firefox/Facebook formats are seen and which ones. I think it would be interesting to do a survey of popular websites and identify which of these are making use of the "ad measurement"/browser phonehome capabilities.

mcc

@dmarti @thomholwerda This entire technology class and the details of its implementation have been way under-reported even in webtech blogs, which normally are falling over themselves to give tutorials on every new browser feature. It's weird considering that theoretically this technology is useless unless somewhere an engineer with a website implements it (maybe there's a separate adtech information ecosystem I don't read?)

Don Marti

@mcc @thomholwerda For the Google stuff you don't need an extension, you can check for an attestation file under .well-known

developers.google.com/privacy-

(just going by market share that seems like it will be the most common one—so far it looks like the Firefox ad tracking feature has resulted in more fediverse+Reddit+Hacker News+LWN posts than actual ads)

mcc

@dmarti @thomholwerda According to Firefox the "ad measurement" feature in 128.0 is not generally available yet. It's locked behind this thing wiki.mozilla.org/Origin_Trials which means each site using the feature has to be individually approved. I don't know if Firefox publishes the lists of who's enabled for which origin trials. They assert the feature is only for "experiments" about whether the feature gathers useful data, but I'd be very curious if Facebook sites are among the ones "experimenting".

Xdej

@mcc
I unfortunately can confirm this for Firefox Focus for Android. By chance, the "reset session" button keeps this state.
@thomholwerda

Firefox Focus for Android at URL  
about:config shows that ad-related setting
dom.private-attribution.submission.enabled  
is set to false. The button "Reset" only shows when this setting is not the default value.
Eragon

@thomholwerda I believe that going in "developer mode" also activate about:config.
For that go in the settings then "About" and tap the Logo (like 10 times I think).
It enable more advanced settings.

Also, Fennec on F-droid seems to either not have that tracking "feature" or it's not updated yet.
It also seems to have about:config enabled by default

James Akers

@thomholwerda Mozilla is making brave browser look better and better every day. I switched to just try it out when I heard Mozilla bought the ad company... I think I might stay with Brave for a bit.

Ben Meier

@thomholwerda thanks! The instructions worked for me. Now I hope the it has the intended effect 🫠

Heretical_i

@thomholwerda I'm getting a blank about:config page 🤔

Kiki

@thomholwerda

Changed it in my Firefox Klar, thanks :)

Fennec (F-droid) doesn't have this field in about:config at all... I assume/hope they just removed that data collection feature completely?

PacificNic

@thomholwerda I don't even know what I just did but if it keeps Facebook out of my shit, I'll trust you, random internet stranger. Thank you.

Louis Vgn

@thomholwerda
What the hell is this thing in the first place?

Whisper

@thomholwerda is there the same issue with Fennec ?

Rix

@thomholwerda thanks, the toggle is so obscure it reminds me of HHGTTG where Arthur Dent is told the plans to demolish his house have been "on display in his local planning office" and he says "I went there and found them 'on display' at the bottom of a locked filing cabinet in a disused toilet with a sign on the door saying 'beware of the leopard'!"
