I use Qwant as my default search engine because I thought it was more respectful of my privacy than Google or Bing and DuckDuckGo is not giving so good results in my country (for localization related searches).

I noticed that the engine was removed from the default engines for URL bar in latest IronFox version. So I searched a bit about why so, and found this issue in their tracker : https://gitlab.com/ironfox-oss/IronFox/-/issues/47.

What to think about this ? The message from ironfox dev seems clear but qwant seems to claim that the shared data are anonymized.
