I haven't seen this posted here, so I will translate the neccessary bits into english. It's really sad what Mozilla is doing and this doesn't help their reputation :/
Mozilla [announced today](https://blog.mozilla.org/press-de/2017/10/06/ein-neues-cliqz-experiment-in-firefox/) that they will start a new experiment next week: **Under one percent of German users who download Firefox from Mozilla will get a version which has recommendation by Cliqz automatically activated**.
Mozilla [invested](https://blog.mozilla.org/press-de/2016/08/23/mozilla-tatigt-strategische-investition-in-cliqz-um-innovationen-bei-der-websuche-im-bereich-datenschutz-zu-ermoglichen/) in the Cliqz GmbH last year. Taken [directly](https://cliqz.com/en/about) from the Cliqz website:
>The mission of the German startup Cliqz GmbH is to redesign the Internet for the user by combining the power of data, browser, and search. In Munich, more than 100 experts from over 30 countries develop browsers and browser extensions with integrated search engines to bring users to their destination in the most direct way while protecting their privacy. Cliqz quick search works with its own independent web index, powered by the company’s Human Web technology. It is available in the Cliqz browser for Windows, Mac OS, Android and iOS or as an extension for the Firefox desktop browser.
>Jean-Paul Schmetz founded Cliqz GmbH in 2008. Since May 2013, Cliqz GmbH has been majority-owned by Hubert Burda Media, one of Europe’s leading media corporations. In August 2016, Mozilla joined as a strategic minority investor. In February 2017, Cliqz acquired the world’s leading anti-tracking tool Ghostery.
There's also a [Cliqz experiment on Test Pilot](https://testpilot.firefox.com/experiments/cliqz) for German users which displays search results in real time. **Cliqz collects data about search and surf activites, including typed text in the address bar. They also collect interactions with the website like how you move the mouse around, spent time on the site, etc**.
The main experiment in Firefox includes this data tool - so they collect the full URL of the sites visited. **This data is send to the Cliqz servers**. This data is "anonymized" and the code is [public](https://github.com/cliqz-oss/browser-core/blob/master/modules/human-web/sources/human-web.es). The cliqz addon can be deactivated and uninstalled of course (normal users may not know how to do this).
How can Mozilla and Cliqz say that they are privacy-oriented when they collect this much data?
