on firefox mobile:

open chrome://geckoview/content/config.xhtml, set general.aboutConfig.enable to true

open about:config, set dom.private-attribution.submission.enabled to false

Wow, thanks for this and the parent post.

What's the difference with setting

    dom.private-attribution.submission.enabled 

to false in the gekoview?

Probably none, I didn't know it was also there. I just compiled what worked for me after scrolling through a few other posts.

Thanks a lot for this tip. I don't know how one is supposed to find this setting.

Yeah on desktop. On mobile it's a lot harder. It's still turned on and you have to use a workaround to enable about: config because they don't bother to make this option visible in settings.

> and you have to use a workaround to enable about: config

I know of no workaround short of installing from the Beta or Nightly channel.

On mobile you probably want to try Fennec and/or Mull, both Firefox forks, compatible with FF addons and available on F-Droid.

As of June Fennec is now under Mozilla?

I can access the about:config page on mobile, but I can't seem to find a relevant option. Maybe it's already disabled for the Fennec app from F-Droid?

chrome://geckoview/content/config.xhtml

Yeah apparently you can use that to set: general.aboutConfig.enable to true

And then you can go to the normal about:config and set dom.private-attribution.submission.enabled to false

Only then is PPA actually off (apparently, I did not manage to test this yet but someone did confirm the default setting is true). Not cool. Especially because Mozilla provides instructions for the desktop version on their site but doesn't even mention the mobile version at all.

Do we know why they blocked about:config on mobile? It doesn't make any sense at all...

It worked for me, no issues. I am on version 128.0 (Build #2016030615)

I had to go through some Gecko thing first like others mentioned, quite odd. Supposedly the setting to adjust is in there too, but I have no idea what applies here

Doesn't work for me

128.0 (Build #2016030615)

Wonder why this is even an issue.

I recently started using Firefox again, because of all the madness around Chrome and the change of how add-ons (mainly uBlock and similar) would work.

And it felt kinda good, i actually thought that Firefox was different and a part of "the good guys", now it doesn't feel that way anymore. Sigh.

I don't know of any "good guys" whatsoever that ever managed to build and maintain a browser. Anyone?

Maybe one day we'll have a usable FOSS browser but I doubt it (the companies will fight tooth and nail against it including legal means, buying out companies, blocking content for them, etc.).

I think the guys that built WebKit originally (Konqueror) are kinda good guys. I still sponsor KDE with a monthly donation <3 But the browser wasn't really kept up, I don't think they had the money for it. It lives on in Safari though.

On MacOS that checkbox is in a separate section called "Website Advertising Preferences".

On NixOS, set

  programs.firefox.policies.Preferences."dom.private-attribution.submission.enabled" = false;

Interestingly the option has a link to an explanation on how it works. Which was handy as I couldn't get past the German cookie dialogue on the original article.

I guess the question is whether the aggregation services can be persuaded by clever attribute manipulation to give the ad site a near unique report for a user across many sites.
