Hi Jonathan,

Can you please have a look into this?

This is intentional breakage, it will only impact nightly and early beta releases.

Users of Nightly who want to use sites like this should flip "security.mixed_content.block_object_subrequest" pref in about:config.

Alternatively (or additionally), ask the developers of the app to change it from using HTTP to using HTTPS.  :)
Also I forgot:

Clicking the (i) icon in the URL bar
You should see: "Firefox has blocked parts of this page that are not secure"
Click the right arrow
Click "Disable protection for now"

Please be careful when using this mode though as it will allow insecure scripts too.
From comment 2, sounds like we don't intend to fix this and it won't be happening on release, at least not for a while.
