Yes. The comment score is queried from HNSearch's API. This extension was my submission to the HNSearch API contest under the name "HN Reveal": http://news.ycombinator.com/item?id=2672793 http://news.ycombinator.com/item?id=2672793 Now, since the beginning of the API contest announcement, HNSearch's API does not reveal score for comments that are less than 5 days old. After studying the API, I figured out a way to bypass this restriction. If you construct a faceted query for the "points" field with a search query that is narrow enough to get exactly 1 hit, the facet result will reveal the vote score for that comment (e.g. "9 points" has 1 hit). When I submitted my entry to HNSearch, Andres emailed me back and told me to disable revealing vote scores for comments that are less than 5 days old. In addition, they modified their API to restrict my query.
