See https://en.wikipedia.org/wiki/Wikipedia:Village_pump_%28technical%29#HTTPS_issues. When browsing https://en.wikipedia.org on Google Chrome, the padlock is normally green (for HTTPS padlock colours, see https://support.google.com/chrome/bin/answer.py?hl=en&answer=95617), but if you'd enabled mwEmbed in your user preferences, it changes to red.
https://en.wikipedia.org/wiki/MediaWiki:Gadget-mwEmbed.js points to http://prototype.wikimedia.org/mwe-gadget/mwEmbed/remotes/mediaWiki.js and prototype doesn't have https set up on it.
This bug is a duplicate of 32457 - mwEmbed is hosted on prototype.mw, meaning that it does not support https *** This bug has been marked as a duplicate of bug 32457 ***
