Unfortunately, as we mentioned in a previous post [1], Mozilla is not totally independent when it comes to the presentation of search in Firefox due to their existing search deals, so they couldn't continue with the integration. This is why we needed our fork.

"It may seem like Common Crawl would suffice for this purpose, but it has poor coverage outside of the US and its update frequency is not realistic for use in a search engine."
These stats are updated monthly, and based on millions of loads of each site. The WhoTracks.Me page for wikipedia.org (https://whotracks.me/websites/wikipedia.org.html) shows that the Google Fonts and Google Static trackers occur very infrequently (<2% of pages), so may be on some part of the site that you did not visit.
While the Wikimedia tracker may seem innocuous, they do set a cookie that is sent in third-party contexts, and have presence across several sites beyond Wikipedia (133 of the top 10k) (https://whotracks.me/trackers/wikimedia.org.html). Theoretically, they could track user sessions across these sites. In reality this is likely an oversight in the server configuration, but objectively this profile looks no different to that of a legitimate tracker.
Google redirects European searchers to Google.com
