Some blogs do not have HTTPS, allow them to use HTTP

Allow sites without SSL certificates to be loaded with http

Hilariously, even though I made the fix to set the protocol correctly, the ssl page still fails to load in an iframe:

[blocked] The page at https://blogofthe.day/? was not allowed to display insecure content from http://thisvictorianlife.com/.

But the RSS is correct. Might need a scheme to set a static image? Shades of #34 @capjamesg ? We could also attempt to pull an og:image or use something like https://github.com/simonw/shot-scraper to grab a shot and put it in as a background image in the iframe
