Interesting.. The search engine selection preconfigured in Ghostery's upcoming browser (based on Firefox) includes a new one called Tailcat, "The open, unbiased search engine." No privacy policy or about page yet that I can find - just that it's based in Munich, Barcelona 🤔
“Today Brave announced the acquisition of Tailcat, the open search engine developed by the team formerly responsible for the privacy search and browser products at Cliqz, a holding of Hubert Burda Media.”
