# Suggest disabling privacy-preserving ad measurement on Firefox **URL:** https://discuss.privacyguides.net/t/suggest-disabling-privacy-preserving-ad-measurement-on-firefox/19372 **Category:** Site Development **Tags:** completed **Created:** 2024-07-09T13:48:39Z **Posts:** 17 ## Post 1 by @BionicBison — 2024-07-09T13:48:39Z With the release of Firefox 128, a new setting for “privacy-preserving ad measurement” has been added and enabled by default. Since PG already recommends disabling this for Safari, it should probably do the same for Firefox. ![Screenshot 2024-07-09 at 9.45.54 AM](//forum-uploads.privacyguidesusercontent.com/original/2X/7/7839acf9a0fb4d4f2a14616f08b8304e601f2e63.png) --- ## Post 2 by @anon80779245 — 2024-07-09T14:34:30Z @dngray --- ## Post 3 by @Kris — 2024-07-09T14:54:05Z How is this setting configured in LibreWolf?

This experiment is only enabled via [origin trial](https://wiki.mozilla.org/Origin_Trials) and can be disabled in the new Website Advertising Preferences section in the Privacy and Security settings.

The box is checked by default, however (at least on my two instances), so it should probably be un-checked to prevent any future enablement of the feature. --- ## Post 7 by @woodruff — 2024-07-09T20:38:43Z I found it enabled by default as soon as I upgraded to Firefox 128. It is also implied here that it will be enabled by default but you can disable it from the settings: [Privacy-Preserving Attribution | Firefox Help](https://support.mozilla.org/en-US/kb/privacy-preserving-attribution) > PPA is enabled in Firefox starting in version 128.

The box is checked by default, however (at least on my two instances), so it should probably be un-checked to prevent any future enablement of the feature. You are right, I was mistaken, it looks to be enabled by default. It seems I misunderstood what they mean by “This experiment is only enabled via origin trial.” As @woodruff’s quoted text alludes to, it seems the opt-in trial experiment is on other end (website owners, not users). I agree, pre-emptively disabling it makes sense until more is clear. And that would be inline with similar recommendations given for Safari and Brave Browser. --- ## Post 9 by @jonah — 2024-07-14T15:48:28Z 7 posts were merged into an existing topic: [“Privacy-Preserving” Attribution: Mozilla Disappoints Us Yet Again](/t/privacy-preserving-attribution-mozilla-disappoints-us-yet-again/19467/2) --- ## Post 13 by @anon97654407 — 2024-07-10T10:05:41Z > > > Changes proposed in this PR: > > - https://discuss.privacyguides.net/t/suggest-di…sabling-privacy-preserving-ad-measurement-on-firefox/19372/9 > > > > > > > - [x] I agree to the terms listed below: >
