I tried both http and https on Firefox and Chrome just now, no problem evident.
In the future, if you think you see something wrong like that, please PM a staff member on line, or at least tag them in a post. Making a thread in Off Topic is about the least likely way to get our attention.
If you click a link where the poster used the "https:" version of the site, you will be on that version of the site until you click a link without it or delete it from the address bar yourself. It's rather annoying at times because user links are what usually put you there.
