Get fucked, advertisers.
Advertisers track you with device fingerprinting and behaviour profiling now. Firefox doesn’t do much to obscure the more advanced methods of tracking.
Don’t all the advanced ways rely on JavaScript?
Lots do. But do you know anyone that turns JS off anymore? Platforms don’t care if they miss the odd user for this - because almost no one will be missed.
“Anymore”? I’ve never met a single soul who knows this is even possible. I myself don’t even know how to do it if I wanted to.
I do use NoScript, which does this on a site-by-site basis, but even that is considered extremely niche. I’ve never met another NoScripter in the wild.
Why not just use ublock medium mode?
Roughly similar to using Adblock Plus with many filter lists + NoScript with 1st-party scripts/frames automatically trusted. Unlike NoScript however, you can easily point-and-click to block/allow scripts on a per-site basis.
https://github.com/gorhill/uBlock/wiki/Blocking-mode:-medium-mode
Am I in the wild? I use it.
I like the grid add-on for Firefox. It disables 3rd party pretty much anything by default. And you can control cookies separately from everything else, and I can’t remember any time I’ve needed to enable those cookies to get a site working properly (whereas sometimes you need to enable scripting, media, or iframe for cdn or something).
uBlock origin + NoScript for me. I deal with the bigger umbrella of scripts with uBlock and then fine tune permissions to the ones that uBlock allowed with NoScript.
They might be fingerprinting me using these two extensions though.
I use LibreJS with few exceptions. If I need to use a site that requires non-free JavaScript, I’ll use a private browsing window or (preferably) Tor Browser.
Not all but most, yes. But TBF, sites that still function with JS disabled tend to have the least intrusive telemetry, and might pre-date big data altogether.
Regardless, unless the extent of a page’s analytics is a “you are the #th visitor” counter, all countermeasures must remain active.
It’s really strange how they specifically mention HTML5 canvas when you can run any fingerprinter test on the internet and see that Firefox does nothing to obfuscate that. You can run a test in Incognito mode, start a new session on a VPN, run another test, and on Firefox your fingerprint will be identical.
Well yeah, they’re just blocking known fingerprinting services. If you use a tool that they don’t recognize, it’ll still work, but their approach will still block the big companies that can do the most harm with that data.
The only alternative is probably to disable WebGL entirely, which isn’t a reasonable thing to do by default.
WebGL
I wish Firefox had a per-site or per-domain preference for WebGL (as well as for wasm, etc), the same way we have per-site cookies or notifs preferences. It’d help clear most issues regarding this.
Honestly would be hard to do. There a perfectly legitimate and everyday uses for pretty much everything used in fingerprinting. Taking them away or obscuring them in one way or another would break so much.
EU outlaws it
The EU isn’t the only place on the planet, even if its laws have an impact.
Yeah, you need uMatrix. although it can be tricky to use.
There is still plenty of fish for advertisers, sadly.
For those who don’t care to read the full article:
This basically just confines any cookies generated on a page, to just that page.
So, instead of a cookie from, say, Facebook, being stored on site A, then requested for tracking purposes on site B, each individual site would be sent its own separate Facebook cookie, that only gets used on that site, preventing it from tracking you anywhere outside of the specific site you got it from in the first place.
Hahahahaha so it doesn’t break anything that still relies on cookies, but neuters the ability to share them.
That’s awesome
Honestly, I thought that’s how it already worked.
Edit: I think what I’m remembering is that you can define the cookies by site/domain, and restrict to just those. And normally would, for security reasons.
But some asshole sites like Facebook are cookies that are world-readable for tracking, and this breaks that.
Someone correct me if I got it wrong.
Total Cookie Protection was already a feature, (introduced on Feb 23st 2021) but it was only for people using Firefox’s Enhanced Tracking Protection (ETP) on strict mode.
They had a less powerful third-party cookie blocking feature for users that didn’t have ETP on strict mode, that blocked third party cookies on specific block lists. (i.e. known tracking companies)
This just expanded that original functionality, by making it happen on any domain, and have it be the default for all users, rather than an opt-in feature of Enhanced Tracking Protection.
That’s not what I was thinking of, which was even more fundamental. But that’s good info (and another way to cover stuff in the article).
Edit: what I was thinking originally was really stupid, that 3rd-party cookies weren’t allowed at all. Which was really dumb since of course they are.
They’ve been doing this with container tabs, so this must be the successor to that idea (I’m going to assume they’ll still have container tabs).
Container tabs are still a thing in FF. This is based on that work, if I remember correctly.
I love container tabs. It’s one of the reasons I went back to FF.
Same, they’re an absolute game changer for me. I have to use multiple different identities in work due to separate active directories and container tabs makes it super easy
Container tabs are still useful, as they let you use multiple Cookie jars for the same site. So, it is very easy to have multiple accounts on s site.
From my experience, blocking 3rd party cookies in general doesn’t seem to make any difference for site functionality anyways. Though I never log into sites with a Google or FB account other than Google or FB sites (and rarely at all for the latter).
I would love to see an icon of a neutered cookie please 🥺😄.
Basically creates a fake VM like environment for each site.
For those who don’t care to read the full article
Or even the whole title, really
Isn’t this basically Firefox’s version of the third party cookie block that Chrome rolled out a few months ago? Or am I missing something here?
I mean, it’s good news either way but I just want to know if this is somehow different or better.
Sites are much more contained now. Is much more like a profile per site.
I don’t know why this wasn’t the case long ago.
It increases implementation complexity of the browser and loses people who fund Firefox and contribute code $$$
I think this tips it over the edge for me to switch to Firefox
I hope so! It’s a wonderful side of the Internet to be on
Really? This is what does it for you?
Ur… Yeah?
I miss Mozilla the product.
I unironically miss Netscape Communicator. Yes most of that went into Firefox but not all and I really miss the frame layout.
I used the shit out of their WYSIWYG HTML editor when I was an up and coming little script kiddie.
Yup. Nobody else gets those cookies.
Aren’t cookies already limited to the site at which they were created??
What the fuck? You mean to tell me sites have been sharing cookies?
I thought all browsers only delivered cookies back to the same site.
The problem is that a website is generally not served from one domain.
Put a Facebook like button on your website, it’s loaded directly from Facebook servers. Now they can put a cookie on your computer with an identifier.
Now every site you visit with a Facebook like button, they know it was you. They can watch you as you move around the web.
Google does this at a larger scale. Every site with Google ads on it. Every site using Google analytics. Every site that embeds a Google map. They can stick a cookie in and know you were there.
Is this also how they know which ads to feed you?
Yes, it’s the reason for the tracking. To sell more targeted ads.
If you’re up for reading some shennanigans, check out the book Mindf*ck. It’s about the Cambridge Analytica scandal, written by a whistleblower, and details election manipulation using data collected from Facebook and other public or purchased data.
Put a Facebook like button on your website, it’s loaded directly from Facebook servers. Now they can put a cookie on your computer with an identifier.
Which is not allowed by GDPR btw, because they do that even if you don’t click them. There are plenty guides online, how to create your own, not tracking, facebook like button.
How does GDPR fit in to Google Analytics and personalised ads?
I would have thought it went something like: random identifier: not linked to personal info, just a collection of browsing history for an unidentified person, not under GDPR as not personal info.
Link to account: let them request deletion (or more specifically, delinking the info from your account is what Facebook lets you do), GDPR compliant.
Both Google and Facebook run analytics software that tracks users. I presume letting people request deletion once it’s personally linked to them is probably what let’s them do it? But I don’t live in a GDPR country, so I don’t know a whole lot about it.
No, it should’ve been opt-in. But loophole with “vital interest” and politics being slow and surface-level like politics.
Is that because the like button is an iframe?
It doesn’t have to be. Your browser sends the cookies for a domain with every request to that domain. So you have a website example.com, that embeds a Facebook like button from Facebook.com.
When your browser downloads the page, it requests the different pieces of the page. It requests the main page from example.com, your browser sends any example.com cookies with the request.
Your browser needs the javascript, it sends the cookie in the request to get the JavaScript file. It needs the like button, it sends a request off to Facebook.com and sends the Facebook.com cookies with it.
Note that the request to example.com doesn’t send the cookies for Facebook.com, and the request to Facebook.com doesn’t send the cookie for example.com to Facebook. However, it does tell Facebook.com that the request for the like button came from example.com.
Facebook puts an identifier in the cookie, and any request to Facebook sends that cookie and the site it was loaded on.
So you log in to Facebook, it puts an identifier in your cookies. Now whenever you go to other sites with a Facebook like button (or the Facebook analytics stuff), Facebook links that with your profile.
Not logged in? Facebook sets an identifier to track you anyway, and links it up when you make an account or log in.
Thank you for the explanation!
How is Facebook able to know what site is requesting it? Is it in the referer header, or is it parameters in the javascript/image url?
There is a referer header sent, but depending on the exact code added to the page, it’s very likely they are loading a snippet of JavaScript that lets them collect other information and trigger their own sending of information to their server.
For example, Google Analytics has javascript added to the page, but loading fonts from Google’s CDN (which many sites do) will rely on the referer.
I know Facebook and Reddit are in cahoots.
I went to visit Reddit a couple weeks back to read the Deadpool & Wolverine comments, but used the wrong container tab and now Facebook feeds me endless Marvel related stuff.
A lot of it is culture war bullshit too. Hmmmmm 🤔
oh i know how this works and its not the way you think. Its somehow better and worse at the same time
Im going to describe the process using a hypothetical situation:
You decide to try a new shampoo but you’re not sure what to buy. You ask your friend “hey what shampoo do you use” and they tell you they use Head and Shoulders.
Later that night, you google head and shoulders and read reviews
The next day, your friend gets Head and Shoulders ads on youtube and facebook and Instagram, etc
This is because google knows both of your locations and search history. It sees that you two were within a few feet of each for hours and decides to shoot ads at you both, based on what either of you have searched recently.
This is called proximity targetted advertising and i think its gross.
But this is why so many people say things like “we were talking about it and now im seeing ads they must be spying on me”
No, you don’t know anything. Just because you have a suspicion because something happened to you once doesn’t mean you are sure in any way.
Nah I’m sure.
I never once saw a post about Marvel fed to me by Facebook and now it’s constant
Did it start after the extremely popular marvel movie “Deadpool and Wolverine” released?
Lol that’s your argument for why you think they don’t know what they’re talking about? Because all you did is make yourself seem like you have no idea how cookies work 🤣
It’s just one single person who noticed something once.
That’s an awful awful sample size absolutely filled with bias and thought fallacies.
Before. “Couple weeks” is more like 5 months at this point now that I think about it.
I don’t mind some of it much, but the obvious culture-war bait is infuriating.
It’s not because the movie just came out. I’ve been diligent about keeping Facebook and Reddit in their container tabs for years. It’s just Marvel stuff, not just the movies. Marvel’s been putting out huge movies for years and this hasn’t happened around any of their other releases.
Why aren’t you just using the official automatic Facebook container?
I made it before that was a thing. Habit I guess. 🤷♂️
NO.
https://en.m.wikipedia.org/wiki/Third-party_cookies
Maybe it’s not allowed in your local jurisdiction? But it’s been a problem since forever.
Why are we posting 2 year old articles as though they are new?
Looks like the article was updated today. I’m guessing this was originally covering an announcement for a future rollout and now it’s finally happening?
this article has not been edited, is from 2022, and says the feature was rolled out in June.
Maybe. Confusing decision on the part of Mozilla though, if so. I was checking to see if they mentioned which version this update happened in, but couldn’t find it. Then I noticed the original post date. Weird.
I guess it says updated, but hey. PR for Firefox is cool, until the imminent enshittification.
The moment that Firefox goes too far, it’ll immediately be forked and 75% of the user base would leave within a few months. Their user base is almost entirely privacy-conscious, technologically savvy people.
Depends on how it “goes too far”. What I am, for example, afraid of is the possibility of removing Manifest V2 support. Maintaining the browser with such a significant change would get more and more difficult as time goes on.
I think that would be an example of a wildly unpopular change, yeah.
This is currently one of the biggest selling points for the browser, since Chrom(ium) is dropping support for v2… So I don’t see that happening.
Sure hope so! But sadly, I think this is a possibility - iirc they were working on a different implementation of Manifest V3, so I fear that it might still happen eventually, “for the sake of security”.
Firefox did an add-on genocide years ago and it obviously didn’t hurt them in the long run.
I agree, but something will have to change because chrome will swallow ALL that. Just today some back-end problem was messing up all my stuff, and co-workers were asking, " did you try a different browser? " botch no I did not try Netscape
“I agree [with the opposite of what you said]. Also, here, have an irrelevant anecdote that includes a funny misspelling and a supposed diss of FF from 1999”
Not sure what you mean - I don’t think most of the people still using Firefox are going to switch to a Chromium based browser any time soon, I can’t speak for everyone of course but it feels like Firefox users tend to have an ideological objection to Google having a monopoly on web browsers.
It’s always worth trying a different browser when you have issues on websites - there are a lot of things that can be different beyond the layout and javascript engines - cookies, configuration, addons, etc. Yesterday I noticed a big difference between Chromium and Firefox in that even if you hard-refresh on a HTTP/2 connection, Chromium reuses a kept-alive connection, and firefox doesn’t — I would totally argue that Firefox’s implementation is more correct, but Chrome’s implementation will lead to a better experience for users hard-refreshing.
Personally, I remember chrome always flash banging me when on a website with a dark background and I clicked to the next page because apparently clearing the page to the same RGB value as what is set as the HTML background is too hard so they just always clear with pure white. But they did have a faster JS engine. Not sure anymore, haven’t given enough of a shit to try anything but firefox in years now.
I meant, talking to coworkers, – yes, I already tried Chrome, Edge, etc, not sure what etc would include - not worth it to explain what little I know of Chromium, and it doesn’t matter. I’m aware it’s Chromium or Firefox in getting a page to work. Random coworkers, they don’t know or care.
Does this make containers unnecessary? Or basically built in?
A lot different. Containers act as a separate instance of Firefox. So any sites you visit within a container can see each other as if you were using a browser normally. The containers can’t see the stuff from other containers though. So you have to actively switch containers all the time to make it work right.
This keeps cookies locked to each page that needs cookies. So a lot stronger.
So what you’re saying is, each site gets its own container?
I think there’s some confusion here. You’re talking about Multi-Account Containers, that person was talking about the Facebook Container. Both Firefox features with confusingly similar names, and honestly that’s on Firefox for naming them.
Facebook Container is similar to this TCP feature, but focused on Facebook. And of course it was a separate extension, so very opt-in. Now, Firefox has rolled it out for ALL sites by default, which is awesome and SHOULD HAVE BEEN HOW COOKIES WORKED IN THE FIRST PLACE!
Isn’t there just a non-extension container feature, I can’t tell what’s the difference between that one and multi-account containers.
Yeah this basically sounds like it takes the temporary container add on that I think was folded into Firefox at some point recently and basically just does it behind the scenes now on a per domain basis
It is making the tracking protection part of containers obsolete, this is basically that functionality but built in and default. The containers still let you have multiple cookie jars for the same site, so they are still useful if you have multiple accounts on a site.
FREEEDOOOOOOOOOOOM
Is this different from blocking 3rd party cookies?
A little. If a third party cookie is set while you’re visiting a site, only that site will get the third party cookie back. Multiple sites can have embedded content making third party cookies, and with this change firefox will track where it was made and only give it back there.
With this change, it doesn’t matter if it’s first or third or whatever; cookies will only be given back to a site that matches much of what is in your location bar.
Mozilla completes what Google was too afraid to finish.
Article from JUNE 14, 2022
Is this the reason why I have to “confirm it’s you” every time I sign into a Google service now? I appreciate the fact that Firefox’s protection is so good that Google doesn’t recognize my PC anymore, but it’s extremely annoying to have to pull out my phone every time I want to watch YouTube.
This might be what finally convinces me to ditch Google for good. Good job, Firefox devs.
No. That’s just Google trying to pester you into using Chrome.
I actually had a problem where on Chrome, I would be signed out of my google account every time I restart my computer, while on Firefox, everything works normally. I use Firefox now lol.
This wouldn’t make you have to log in every time you watch YouTube. It means by signing in to google.com, youtube.com can’t tell that you’re signed in. If you sign in on youtube.com, you’ll stay signed in on youtube.com unless you have something else deleting your cookies.
Well have had my cookies set to delete every time I close the browser for several years now but FF only now started doing this verification thing. A week ago all I had to do was enter my email and password.
If you’re already deleting all your cookies every time you close, then this new change should be identical to your first login of the day when your browser has no cookies. If you’re only getting 2fa requests after this change, then maybe you weren’t actually deleting every cookie, and Google was still fingerprinting you somehow.
This article is from 2022
It was updated today. 2 years ago it was just an announcement of a beta function in private browsing, the full rollout happened with 129.0.2 which was released a few days back.
Cool, thanks. How’d you find the version number? I was looking on the linked post but didn’t find it. Maybe just me being tired.
I don’t think it was in the article, but I updated to 192.0.2 yesterday and checked the enhanced tracking protection settings, and block cross-site cookies is now in the default profile, so that was my assumption since it wasn’t there previously.
I wonder how long until all the distros have this.
This is old news, from 2022!!
From the blog post:
“June 14, 2022”
“Updated Aug. 28, 2024”
“And starting in 2024, all our users can look forward to Firefox blocking even more third party cookies.”
Except it’s still out of date because it mentions chrome also blocking third party cookies when at this point in time they’ve announced that they’ve abandoned that course of action now.
Starting in what versions?
Forgive me if this is an overly simplistic view but if the ads with cookies are all served on Google’s platform say then would all those ads have access to the Google cookie jar?
If they don’t now then you can bet they are working on just that.
The way I’m reading it, they allow the third party cookies to be used within the actual site you’re on for analytics, but prevent them from being accessed by that third party on other sites.
But I just looked at the linked article’s explanation, and not a technical deep dive.
So that’s what third party cookies are. What this does is make it so that when you go to example.com and you get a Google cookie, that cookie is only associated with example.com, and your random.org Google cookie will be specific to that site.
A site will be able to use Google to track how you use their site, which is a fine and valid thing, but they or Google don’t get to see how you use a different site. (Google doesn’t actually share specifics, but they can see stuff like “behavior on one site led to sale on the other”)
We’ll have to see what happens but what you are talking about is what Mozilla calls Third-Party Cookies and… they are aware of it.
I can’t entirely tell if that means they will be put in the facebook cookie jar or if it will be put in the TentaclePorn Dot Org (don’t go there, it is probably a real site and probably horrifying) cookie jar. If the former? Then only facebook themselves have that which… is still a lot better I guess? If the latter then that is basically exactly what we all want but a lot of sites are gonna break (par for the course with Firefox but…).
The cookie would go to the Facebook or tentacleporn cookie jar depending on which site the user has actually visited. Whatever the domain in the address bar says.
InB4 the guy who replies to defend tenticle porn…
They are usually separate things. Cookies are produced/saved locally, to be read in the next visit (by the same website or maany websites basically forever unless you use firefox containers or at least clear them once in a while). There’s also local storage which is different but can also be used to identify you across the web. Ads, trackers, all of these categories are often made of many small components: you read a single article on a “modern” newspaper website, hundreds of connection are being made, different tiny scripts or icons or images are being downloaded (usually from different subdomains for different purposes but there’s no hard rule). It’s possible to block one thing and not another. For example I can block Google Analytics (googletagmanager) which is a tracker, but accept all of Google’s cookies.
