this is concerning to me. not only is google the default search engine, but it has autocomplete enabled, too. much of the value of librewolf is its default configuration; if that's not being applied, what else might be missing?

the problem isn't wrapFirefox as far as i can tell; this still happens with librewolf-unwrapped
