I searched “YouTube adblocker” on both google and DDG. The first mention of ublock origin was in the 1st page of Google (just at the bottom, under “recommended adblockers for Firefox”, the 2nd option). There was no mention of it on DDG, even though I clicked “more results” once (so searched the equivalent of 2 pages). The problem with Google search is not google, it’s SEO, that affects all search engines.
