I've also seen it noted as a new "feature". Agreed, a pain, since the vast majority of web sites do not offer https - costs quite a bit more for the owner of a low-cost site (cost of SSL cert) and it's a lot slower, taking up more processor time and hence slowing down large or heavily-loaded virtual servers. Also, you have to serve images from SSL since the browsers complain if you have mixed content; and since total image size is often much larger than a page this compounds the problem. Unless the site has sensitive data etc (shopping carts, submitting personal details etc) there is usually no reason for SSL, even if b... G tries to convince their gullible customers otherwise.
It is probable that about:config will have a switch for this, but turning off auto-complete may also work.
