Firefox 128 has tracking / "ad measurement" enabled by default

According to several sources, for example https://mstdn.social/@Lokjo/112772496939724214 https://heise.de/-9801279 Firefox 128 has user tracking (including sending data to advertisers) enabled by default, which breaks the privacy expectation Firefox users often have. I'd recommend to change the default for the "Allow websites to perform privacy-preserving ad-measurement" to disabled. If someone really wants to be tracked to support the ad industry, they can easily enable that option ;-)
While I understand the concerns in general I find it hard to decide what to do. Here is another discussion which gives more context about the "feature". https://www.reddit.com/r/firefox/comments/1e43w7v/a_word_about_private_attribution_in_firefox/
