Firefox just updated and those shit eaters decided to add some ai slop search engine to the browser so make sure to go under your search settings and remove it like I'm about to.
@radicalrobit also you can go to https://mycroftproject.com/ and add search engines for things you actually want to use (wikipedia, archive.org, etc.)

@apocheir @radicalrobit Thanks very much! For anyone who wants it, I just installed the no-AI version of DuckDuckGo from this page: https://mycroftproject.com/install.html?id=123469&basename=ddg_noai&icontype=ico&name=DuckDuckGo+-+no+AI

I didn't see any Page Actions "..." in the Location Bar, but maybe that's because I keep a separate Search Bar. The magnifying glass icon worked fine for me.
