This post recommends the Newsit extension to view Hacker News discussion associated with a page. In the same vein, a few years ago, I made a Firefox extension for users who want a privacy-preserving way to see if pages have associated HN discussion: https://addons.mozilla.org/en-US/firefox/addon/hacker-news-d... Most other extensions probably hit an external API (such as Algolia) to check submission status, which means they send every page you visit to that API. Instead, my extension uses Bloom filters compiled from every link ever submitted (updated daily from the Hacker News BigQuery dataset) to check the current page's submission status. By using Bloom filters, my extension only hits the API when you click the button to view the discussion.
