I love the idea of showing a different icon for HTTP... however, I personally think the icon is too close to the lock icon (some browsers show standard SSL as gray lock and EV SSL as green).

I'm curious what others would think about changing this to yellow or orange and then using a more obvious icon to represent HTTP. Something like:
fa-exclamation-triangle
fa-times-circle

or for comedy purposes:
fa-frown-o

@bsclifton Thanks for the feedback. I thought about it too, but yellow or @BraveOrange should be reserved for worse scenarios until #1576 will be merged IMO.

I like how this makes HTTP and HTTPS look more different from each other, so +1. Agree that we should consider making HTTP look scarier as @bsclifton suggested.
