Why has Firefox not removed third-party cookies, despite the fact that Chrome has begun phasing them out? - lemy

They will likely remove them soon I suppose. And it’s easier to leave the option available in case it breaks someone’s use-cass until they fix it.
I think they took a different approach and block known trackers but not all cookies.
Blocking third-party cookies is a more effective way to protect user privacy than blocking tracking cookies, because third-party cookies can be used to track users across multiple websites.
Yes, but known 3rd party tracking cookies are already blocked. It’s not like these tracking sites pop up every day, but the list is updated when new ones are found. Meanwhile, 3rd party cookies for legitimate uses are allowed.
It’s been an option for as long as I can remember. I suppose they are leaving the default until websites adapt to chromes changes.

Firefox blocks known trackers and isolates third party cookies per site. They do have legitimate uses, and not every site has made the switch to modern tech that could replace it.

Saying goodbye to third-party cookies in 2024 | MDN Blog

The tail end of 2023 welcomes positive news for web privacy, as Chrome announces it is to join Firefox and Safari in deprecating third-party cookies in 2024. Find out more details about these changes, and what they mean for web developers.

That's the superior approach and Firefox introduced it far earlier than Google addressed the problem.

Why OP is blindly arguing in that corp's favor and ignoring all the reasoning provided here, is beyond me. Shilling?

Yeah my company uses them for integrating some of our apps together. They aren’t used for tracking at all, and we’d be up shits creek if they were, because our (corporate) customers audit that sort of thing.

Because of Google we’ve had to develop an alternative solution which has taken years to develop and is only getting deployed now. Those fuckers have way too much power over the Internet.

I’m confused. Didn’t this start at the beginning of last year?

Firefox 86 Introduces Total Cookie Protection – Mozilla Security Blog

Total Cookie Protection is a major anti-tracking advance in Firefox that confines cookies to the site where they were created.

Mozilla Security Blog

I’m pretty sure that Chrome’s alternative is designed by Google to track you in a way that’s harder to block and gives them more control over the advertising market by forcing advertisers to play along and use their method instead of collecting your data directly. Sure, it’s more private, but it’s still tracking you.

Firefox, on the other hand, is focusing on completely blocking cross-site tracking. They have no incentive to completely block 3rd party cookies as long as there is also a legitimate use case for them, but I guess they will eventually also block them if Chrome is successful in forcing websites to stop relying on them for core functionality.

Chrome is Enhancing Your Web & Ads Privacy - Google Chrome

Chrome is innovating ways to protect your privacy on the web. Explore the enhanced web and ad privacy protections we designed to keep you safe online.

Not sure how Chrome’s alternatives for providing relevant ads are harder to block when you can just turn them off (and examine the data it’s collected) in the settings. These systems are what Chrome is able to do at the moment to work towards blocking third party cookies. They do have an incentive to make something that they know works well for them though, I’ll give you that.

Is that part of the chromium engine which is open source or is it closed source ? Because if it’s not visible it doesn’t matter what Google tells you.

It’s part of the open source chromium engine.

Here’s how it implements some of the privacy sandbox stuff for example: chromium.googlesource.com/…/privacy_sandbox/

Theoretically they could still inject malicious code even if the stuff in the chromium source code looks fine. Given they got sued for their servers still tracking you while Chrome was in Incognito mode (even with the warning every time you open Incognito mode), I’d imagine any injection of code like that would result in another lawsuit (or several). At some point you either have to trust that Google is implementing things how they say they are in the code that they put out or just use a different browser.

I checked your link but as most people I’m not programmer, so we can’t check or even remotely understand what Google engineers does. On the other hand, what common people can understand is 'follow the money ́. Google makes most of its money on selling personalized ads, the more data they get on you the higher advertiser will bid.

It would make absolutely no sense, financially, for Google to reduce it’s tracking ability and let the user decide which ad they want to see or not.

And at the end Google is a business, money goes in, more money goes out. They could be doing what they claim to do right now, only to change in 2 years when all third party advertiser are bankrupt because they can’t use cookies anymore. That’s another possibility.

The way I see it, Google knows that changes are coming to the advertising industry, either through regulations or just public opinion. By doing this now, they can try to get ahead of those changes/criticisms while controlling what systems their advertising competitors will have to operate under. I don’t doubt that Google will still have enough data to do relevant advertising, either with the data from these new systems in the browser or the first-party data they have on people through their sites.

Why would an open source browser remove a feature just because a corperation did it. Talking like that, might as well use Chrome. Oh wait. But it’s spware/ anti AdBlock.

Why doesn’t Firefox make AdBlock harder since Google does the same? Firefox isn’t competing for Market share, it’s suppose to be an Opensource browser and being so should mean that you have the best features for the user, and not a company.

Had you ever asked why would Google get rid of 3rd party cookies, and also ask, what did they replace 3rd party cookies with? another way for them to track you, and only them. They took potential revenue from sites that aren’t them just because they can.

Third-party cookies make tracking users easier. I am not asking Firefox to follow Chrome at each step.

I am just asking for the privacy browser to improve users’ privacy by removing support for third-party cookies, because it theoretically will not break anything.

I do agree, that removing it would improve user privacy, however I feel that should be up to the user to decide on their own if they want or don’t want third party tracking cookies as it has been.

The alternative that Google proposed I don’t think it’s any better then what is was before with 3rd party tracking cookies. I’d say it’s worse since it introduces new problems while keeping old problems under a new name.

If everything goes through Google, no one has personal control and that’s what i’m against. This encourages what open source users should be against.

I’m not sure how moving stuff like topics of interest into the browser where it can be modified/turned off by the user in a single, local location isn’t an improvement over the current situation?
Because google is still tracking you. They are just getting rid of third party cookies being able to follow you on the web. They have fingerprinted the chrome browser itself, so every instance of it is unique to the individual using it (or their hardware) with the intent of continuing to track you while making it difficult for other third parties to do the same. And they’re using deceptive language to make it seem like that’s not what’s happening. That language may not work on everyone but it will work on the vast majority especially of younger gen people who just aren’t as tech savvy despite how much tech is integrated into their lives.

Yes, Google isn’t getting rid of tracking in it’s entirety, they’re just getting rid of the tracking competition on the Chrome browser. And no one has the guts to make their own commercial browser to stick it to Google and their monopoly, all we really have are open source browsers. Even Edge has to be open source to an extent since they borrow from Chromium.

I wouldn’t go so far as to just assume that all younger gen people aren’t tech savvy. I guess it would just depend on the person and how casual or into tech they really are.

3rd party cookies make tracking users easier when the same cookie can be used on many websites.

Firefox does 2 things to protect you from that: it blocks known trackers cookies by default; and for the others it isolates them per domain so that kind of tracking doesn’t happen. That ensures you’re not tracked and at the same time it doesn’t break any functionality.

If you want to completely block them you can. There’s more info here: …mozilla.org/…/third-party-cookies-firefox-tracki…

I believe Mozilla said it best here:

blog.mozilla.org/…/improving-privacy-without-brea…

Firefox’s privacy protections must be usable on the web, or people will simply stop using Firefox altogether.

The web is not at the stage yet where third-party cookies can be disabled entirely. Chrome’s phase out of them this year should push all those sites still clinging to them to fix their sites. This should mean less problems when using Firefox’s privacy features. Firefox won’t necessarily need to remove the feature soon anyways since it already isolates them per site.

Firefox has been able to block all third-party / cross-site cookies for ages. It’s just not the default because it breaks some sites. But dive into the settings and you can easily set it to block all cross-site cookies, or even all cookies if you prefer.

There’s a check box in FF settings to block all third party cookies.

You should probably educate yourself before making inaccurate claims.

Is it default? Idk
No because some pages might break
The option to disable third party cookies has been in pretty much every browser (Chrome included) for decades. OP is talking about Google’s move to make it the default.
Because Firefox chose a superior approach and Google was late addressing 3rd party cookies in the first place. Why did Google not adopt Mozilla's superior approach of isolating 3rd party cookies per domain?
Mine has been blocking for years now. It’s already there, just not on by default. It does break some sites so am assuming that’s the reason. I just got use to the fact some sites will stop working and moved on.
