Firefox 128 has a new feature called Privacy-Preserving Attribution or ppa for short
enabled by default without an option in the settings to turn it off
however it can be disabled using about:config or a user.js file in your Firefox profile

For the last few months we have been working with a team from Meta (formerly Facebook) on a new proposal that aims to enable conversion measurement – or attribution – for advertising called Interoperable Private Attribution, or IPA.
IPA aims to provide advertisers with the ability to perform attribution while providing strong privacy guarantees. IPA has two key privacy-preserving features. First, it uses Multi-Party Computation (MPC) to avoid allowing any single entity — websites, browser makers, or advertisers — to learn about user behavior. Mozilla has some experience with MPC systems as we’ve deployed Prio for privacy-preserving telemetry. Second, it is an aggregated system, which means that it produces results that cannot be linked to individual users. Together these features mean that IPA cannot be used to track or profile users.
Heres how to disable it in Firefox 128
method 1 - about:config
Open about:config in the Firefox urlbar ( or whatever you call it )
paste in the following code in the about:config search
by default it will say true,
double click true and it will toggle to false
method 2 - user.js
open about:support in the urlbar
and you will see the location of your profile directory and a button to open the directory in your file browser
create a user.js file in your firefox profile directory with the following content
restart firefox and open about:config
paste in the following code in the about:config search
and you will see its now set to false
however if you look in the firefox settings page you will notice there is no change shown in the gui
its a bit confusing because the checkbox is unchecked by default
which makes you think its not enabled
clicking in the checkbox doesnt do anything
thats why you have to use about:config or a user.js file
i would recommend using a user.js file as it keeps track of all your settings
and can be transferred to another computers firefox profile directory to apply all the same settings
much easier than pasting stuff into about:config
my user.js file
enabled by default without an option in the settings to turn it off
however it can be disabled using about:config or a user.js file in your Firefox profile
