Doesn't work for me, but probably because the machine I usually use to access HN is running Firefox 1.5 on SuSE 10.1. One of the things I love about HN is that it runs prefectly on such an old browser/OS combination.
EDIT: Wow, a downvote despite providing concrete feedback to the submitter? Interesting. I might have to re-think my entire position about the HN "community" as expressed here: http://news.ycombinator.com/item?id=2660578
