Hacker News Room <a href="http:&#x2F;&#x2F;hackernewsroom.com" rel="nofollow">http:&#x2F;&#x2F;hackernewsroom.com</a> is a web-based HN reader, built on the official HN API. It&#x27;s not a browser extension, but it has some nice features including folding comments. And it works well in all modern browsers.<p>Disclaimer: I built it.
