I've been using HTTPS-Everywhere for a reasonably long time now (a couple of years?) but this is actually the first time I've added a rule...so if anyone else falls into that boat: all you need to do is save the YCombinator.xml file (linked above, from Mike's GitHub) into the HTTPSEverywhereUserRules folder in your Firefox profile folder, then restart Firefox.
Hopefully that'll save someone else from having to look it up ;)
