In a blog post, Firefox's parent company Mozilla has explained that this new feature is an experiment designed to shape a web standard for advertisers, one that relies less on cookies but still tracks you in some way.
With privacy-preserving ad measurement, sites will be able to ask Firefox if people clicked on an ad, and if they ended up doing something the ad wanted them to.
Even though Mozilla's intentions appear to be genuine, this feature should never have been enabled by default, as no matter its label, it still does technically give advertisers your data.
