None of the solutions work in this thread work for me. Firefox 45.0
Same issue myself. Did some digging, and it might be related to this issue:
Looking into the Firefox debugger, found where the local CSS is being set:
In the JS console, compared document.styleSheets0; on the main page to what is pulled on the iframe alone (via Right-Click→This Frame→Open Frame in New Tab).
In main page: https://cdn4.kongcdn.com/compiled-assets/gamepage_merged-cd2a25d9d4f23c555aea10d17698d73e.css
In frame-only tab: http://game255124.konggames.com/gamez/0025/5124/live/TemplateData/style.css
So it might be an issue of the wrong CSS document being selected, and therefore throwing the security exception when attempting to access its cssRules property/attribute due to the wrong CSS being on a different domain from the running JS.
