So I had this little issue earlier where the Flash games I was hosting on my site (Hippo Gram, Haunted Theme Park, Narf's Sheep Hunt) wouldn't show up in certain browsers (Chrome) because the Flash games (hosted on Amazon S3 because Squarespace 6 isn't nice about that kind of thing!) were unsecure ("http://") and Squarespace 6 likes to default you to secure ("https://").
Well, thankfully, Amazon S3 recently re-jiggered things a bit and the link they provide for hosted files is now secure by default! So I changed everything up, removed the annoying disclaimers on the game pages, and Chrome should no longer have any trouble showing my games. Thanks Amazon!
