Floating Social - insecure content blocked

The stubmleupon image is blocked because it tries to load from an http page.
How do I get the content to load from https?

See below the console error message:
Failed to load resource https://www.reddit.com/static/button/button2.js
event.returnValue is deprecated. Please use the standard event.preventDefault() instead.

It looks like there is a reddit js problem too?

Thank you for your time.
