This post, when viewed in HTTPS, is triggering security warnings:
Using Firefox, I got the classical yellow triangle warning in the address bar, caused by this
img tag with absolute URI source in HTTP:
<img alt="Snowden pulling blanket over his head" src="http://i.stack.imgur.com/bDeLe.png">
In Chrome, I got the grey shield warning and this error in console:
Mixed Content: The page at 'In CitizenFour, what was Edward Snowden mitigating with a head blanket?' was loaded over HTTPS, but requested an insecure script 'http://stackexchange.com/ads/beta-question/js?id=beta-ad-container'. This request has been blocked; the content must be served over HTTPS.
Including HTTP resources in a page served in HTTPS is generally considered an issue https://developer.mozilla.org/en-US/docs/Security/MixedContent/How_to_fix_website_with_mixed_content
Should that be fixed?
