STOCKHOLM, Sept 25 (Reuters) - Vienna-based advocacy group NOYB on Wednesday said it has filed a complaint with the Austrian data protection authority against Mozilla accusing the Firefox browser maker of tracking user behaviour on websites without consent.

NOYB (None Of Your Business), the digital rights group founded by privacy activist Max Schrems, said Mozilla has enabled a so-called “privacy preserving attribution” feature that turned the browser into a tracking tool for websites without directly telling its users.

Mozilla had defended the feature, saying it wanted to help websites understand how their ads perform without collecting data about individual people. By offering what it called a non-invasive alternative to cross-site tracking, it hoped to significantly reduce collecting individual information.

    While it was kinda lame for Mozilla to add it with it already opted-in the way they did

    That’s really the rub here. Reading the technical explainer on the project, it’s a pretty good idea. The problem is that they came down on the side of “more data” versus respecting their users:

    Having this enabled for more people ensures that there are more people contributing to aggregates, which in turn improves utility. Having this on by default both demands stronger privacy protections — primarily smaller epsilon values and more noise — but it also enables those stronger protections, because there are more people participating. In effect, people are hiding in a larger crowd.

    In short, they pulled a “trust us, bro” and turned an experimental tracking system on by default. They fully deserve to be taken to task over this.
