Ok. Because I seemed to be the only one with these problems, I tried the whole withdrawal process once more in a different browser (Chrome instead of Firefox) and it worked! I finally got the confirmation email. Will post here if/when I receive the funds.

The newest firefox build has issues with a lot of sites. It's on the paranoid side about https and where it will and won't submit data etc. It frequently flags stuff that is https as not being so.

If you get a warning box saying some elements are insecure switch to chrome or something like palemoon/comodo dragon.
