As mentioned in issue T817 purebrowser shows Firefox Home page with quick links to proprietary services (youtube, google, amazon) - as well on new Tabs.
Maybe its good to investigate deeper which of those Links actually appear to annoy us.
Youtube, Google and Facebook are sadly still famous websites. I recommend only removing of the two shopping Links: Amazon and Ebay.
Additional ideas if we really want to remove Google Search and Youtube too:
https://start.duckduckgo.com/ instead of Google Search. We have already consens in DDG is the standard search engine in pureborwser. start.duckduckgo.com is the clean search-only page of DDG (without popups appearing on duckduckgo.com, ddg.gg, duck.com)
or https://startpage.com - is its giving Google results while protecting users privacy.
