In 2014 there was this article: https://fossbytes.com/yahoo-replacing-google-become-default-search-engine-firefox/<p>I remember when Firefox used to show Yahoo as a search engine choice in settings. Today it's missing. It appears one can search for one of several addons and hope to get one properly supported by Yahoo. [Edited to be nice.]
I remember seeing that yahoo default option, then having to switch it back to Google (so this was long enough ago I didn't use DDG/Kagi), but I never noticed them remove yahoo outright as a search engine option. But indeed, it is gone.<p>The official addon (at least its username checks out, but might be a squatted username) appears to be [1].<p>I can't even comment on why Yahoo! was removed except to speculate that perhaps Mozilla no longer had a contract to give them trademark permission to include Yahoo in their default search engine list?<p>[1] <a href="https://addons.mozilla.org/en-US/firefox/addon/search-and-new-tab-by-yahoo/" rel="nofollow noreferrer">https://addons.mozilla.org/en-US/firefox/addon/search-and-ne...</a>
