On the CDN urls, you can just change them to use protocol relative urls. It Looks like the jquerytools cdn doesn't support HTTPS, but you should be okay to use this one from cloudflare

//cdnjs.cloudflare.com/ajax/libs/jquery-tools/1.2.7/jquery.tools.min.js

Here's a texpaste showing what you should change your script src's to. https://texpaste.herokuapp.com/n/lyoitffa

Note that this won't work for MathJax, since the certificate won't match the domain. For a workaround: http://www.mathjax.org/resources/faqs/#problem-https

> protocol relative urls.

Fun bit of trivia: these are actually called 'network path references.' http://tools.ietf.org/html/rfc3986.html#section-4.2

Thank you for going the extra mile.

On a seperate note, I'm surprised that people actually try it on the https version (or be extra careful and manually add the https).

HTTPS Everywhre does it automatically for known sites that support https, eg. *.herokuapp.com

Many have plugins in their browsers that automatically try to get the https version of any website.
