According to privacyguides.org and nostr:nprofile1qyt8wumn8ghj7un9d3shjtnddaehgu3wwp6kytcqyq489zwer8xa855m05nqwh2swv89u2dmyesznz20n5edpnl74zzr7flnsku it is a good way to use firefox together with arkenfox userscript and uBlock Origin plugin, when you want to improve your privacy.

Both tools also deliver good documentation about privacy from trackers. But I think already using Firefox or Brave browser together with a privacy oriented search engine will give decent privacy improvement compared to 95% of internet users.
