[Hummingbird Pro] Hummingbird causing mixed content errors and broken fonts

Hello,

I've got an issue where Hummingbird keeps breaking my web fonts, including the search magnifying glass turning into a U. I have isolated it to Hummingbird, so for now I've disabled Hummingbird on my site.

I isolated it by choosing "see this page unminified" under the Hummingbird menu and the problem goes away.

The strange part is I have NOTHING combined or inlined in my settings. I have some things individually compressed, but even then not most of the stuff. Please advise. I have turned on support access for the site on this ticket so you can check it out.
