No Firefox does not have its own search engine. I wish it did as it would more focused on privacy than Google. But [https://duckduckgo.com DuckDuckGo] & [https://www.startpage.com/ Startpage] appear to be two very privacy focused search engines. So that's two alternative options for you. Firefox also relies on other search engines like [https://www.ecosia.org/ Ecosia], [https://www.qwant.com/ Qwant], Startpage, Google, Bing, and Yahoo. Since Firefox can't build its own search engine, it partners with companies who build them. See one example of Firefox's partnership with the Ecosia search company: https://blog.mozilla.org/en/mozilla/firefox-ecosia-partnership/ https://addons.mozilla.org/en-US/firefox/addon/ecosia-the-green-search/

Mozilla Firefox or Firefox for short is a web browser. Mozilla the makers of the Firefox web browsers does not have a search engine of their own. https://support.mozilla.org/en-US/kb/add-or-remove-search-engine-firefox The https://mycroftproject.com/ also has a long list of search engine options to choose from to add to Firefox also.
