Suppress Google FLoC on all websites when Tracking Protection filter …
Browse files Browse the repository at this point in the history 
…is enabled

Google started experimenting with FLoC in Chrome browser. This new API is supposed to replace third-party cookies and allow learning about users behavior in a more privacy preserving way than it was.

We are pretty sure that people who use AdGuard Tracking Protection filter are not okay with websites learning about their behavioral groups regardless of how preserving it is.

There's an article by EFF explaining issues of this new API and we agree with every point there:

@ameshkov Hello. I propose that AdGuard should create a scriptlet similar to what uBlock Origin had done. Take a look.

I agree add *##+js(no-floc) for uBO users.

or *#%#//scriptlet('set-constant', 'document.interestCohort', 'undefined')

That scriptlet is pretty much the same as the rule I've added.

I guess we'll add it for compatibility purposes, but generally, I don't see any real need for it besides that: AdguardTeam/Scriptlets#124

What's more interesting in that commit is using Permissions-Policy header for disabling FLoC.
I want to add a separate rule modifier for modifying this header, just like what we have for $csp: AdguardTeam/CoreLibs#419

Read this header spec just in case, it allows doing some pretty neat things like disabling geolocation, battery API, vibration access, etc, etc.

Is it integrated in the products yet? I am quite happy by AdGuard's improvement time to time.

There's no need for software updates, just make sure that Tracking protection filter is active and then check for filter updates in your AdGuard app/browser extension.

@krystian3w scriptlets in general are possible with Manifest V3. Headers modification will also be possible.

Settings -> Ad Blocker -> Add filter -> Choose "AdGuard Tracking Protection filter" (if it's not enabled already)
