Blocking FLoC is as easy as adding this header to the HTTP response: Permissions-Policy: interest-cohort=() Source: https://www.drupal.org/project/drupal/issues/3209628

So, wait. We add this into the headers, and just expect Chrome to respect it?

It's that or stop using Chrome

What I don't get about the reporting on this topic: Isn't all this opt-out stuff just necessary while Google is testing FLoC and it'll be opt-in(!) after it leaves Origin Trial phase? Or is this Google employee straight up lying* here? https://twitter.com/Log3overLog2/status/1384337637763387394?... * I don't suspect he his.

All of the reporting is ignoring this fact because everyone who's commenting on this issue is ignoring this fact in favor of their own assumptions about how the platform works. "Opt-out for testing, opt-in for production" has been the design from day one, but a lie can run 'round the world before the truth has got its boots on.

(And while the author does say "Best guess", this isn't just an empty Google promise—if this changes, it would change the entire tenor of consensus-based standardization discussions that are happening here, and significantly lower Google's standing in the web standards community, which they care a lot about)

> There is a caveat regarding FLoC blocking on Whole Foods pages, however. While other Amazon-owned domains mentioned here that block FLoC do so using Google’s recommended approach involving sending a response header from HTML pages, Whole Foods blocking employs a tactic that sends an opt-out header from Amazon analytics requests. What do they mean here, that the actual page request does not send the "no FLoC" HTTP h…

Amazon has a pretty big advertising platform too , I think they’ll try to spread this header on all the websites that use their ad platform.

So they might be trialing it this way because of that, to help boost their ad platform and hinder floc , so that google cannot drop third party cookies that easily , as floc’s on browser processing makes google the defacto judge on what information do they add into floc identifiers and what they do not , meanwhile themselves getting all the unrestricted data from their browsers separately.

By hindering mass scale adoption of floc , they’re trying to delay dropping of third party cookies , to slow down google from getting an advantage over them.

Atleast that’s what I think , they might be testing it for other reasons, only an Amazon exec can answer it specifically.

It speaks volumes that Google allows many ad blocking extensions in Chrome Web Store, but blocked an extension that was doing exactly that: https://adnauseam.io/free-adnauseam.html

Does that actually work? It seems like clicking on every ad would be easy to filter out.

Probably, but it would "trash which "cohort" Google thinks I belong in"; there's really no reason to fool Google into putting you into a specific cohort as opposed to just a random/"broken" one; either way, your true cohort is obscured.

Unless you were studying the impact of ads you receive based on cohort, like https://their.tube.

Trying to block this is a losing battle. The whole privacy-first angle is so disingenuous, too. Is there a way we can just obfuscate / ruin our data with them? Like a tool or browser extension I can run that clicks / visits a bunch of random links and totally trashes which "cohort" Google thinks I belong in. I'd pay for this more than paying to opt-out. Then serve me all the ads you want.

Just don’t use chrome ? Or if you really like chrome Use a chromium browser that won’t implement cohorts , why bother feeding it disingenuous data instead of just not feeding it anything ?

The website is really a third party here, the browser is choosing to track users browser history and report a summary statistic on it to anyone who asks, there's nothing the website can do about that. Chrome has promised to listen if websites say they don't want to be included in the browser history they calculate that statistic on, but it's all client side, there is nothing the website can actually do but request th…

Really? Because that is how googles documentation says it works: https://web.dev/floc/#how-does-floc-work

If Firefox had larger market share, Chrome wouldn’t have been able to make this opt out for websites rather than opt in because it would have given them a bad public image. I don’t think it’s fair that some company gets to force every website maintainer (most aren’t extremely technical and just use Wordpress or something similar) on earth to muddle through documentation for their particular setups to 1) learn it exis…

I would love to use Firefox, but for some years now Firefox on the Mac (when I have a few dozen tabs open) causes multi-tens-of-seconds pauses whenever I do anything with the mouse like click or scroll. Some of these throw up a rainbow cursor; some just silently do nothing. And yes, I'm using the latest version of everything, including hardware.

While Mozilla obsesses about eye candy, they lose market share because they cannot be bothered to fix decades-old memory management problems in Firefox such that:

1. Memory leaks don't happen,

2. Garbage collection happens silently in the background, and

3. Garbage collection actually frees up memory for new allocations.

This seems like pretty basic stuff; Chrome figured out how to make tabs scale at close to O[1] a long time ago, but in Firefox tabs still feel like they scale as O[n^2].
